75 gallon tank journal​

Finally, I forced myself to sit on a computer and start writing a tank journal of my recently started 75G AGA planted tank. This is my second planted tank (I switched from 15g) and the first properly thinked over, planned and set up in my “career”. It took me a lot more time than I thought to fill it with water and I hope it’s worth the time and effort. You can find my DIY stand building thread in my signature if you’d like to find out how this project started.
I’d like to thank all of you for support and advice, this forum helped me a lot with understanding planted tank nuances. Special thanks to Left C for helping me assembling my regulator, oldpunk78 for his help and plants he gave me, Torpedobarb for MTS and a helpful info and all RAOK’ers and kind people on the forum- I owe you one

WATER PARAMETERS:
Temp: 80 degrees
Kh from the tap: about 4dKh
Ph: 6.5
FERTS:
None at the moment, it’s MTS for gods’s sake We’ll see how long I can get without ferts

Fauna:
9x rummy-nose tetra Hemigrammus rhodostomus
8x Ottos Otocinclus affinis
3x juvenile Discus (turquoise blue, but I can be wrong, you judge)- I just couldn’t refuse to take them whem I saw them in LFS
Pair of German Blue Ram Mikrogeophagus ramirezi
7x Panda Cory cats Corydoras panda
Pair of Madagascar Rainbow Bedotia geayi
I am planning to transfer some adult RCS from my old tank, which is a CRS colony tank at the moment, hoping that they’ll survive with my fish.
Flora:
Two things- I suck when it comes to IDing plants and two: it’s a mess without any ‘serious’ scape at this time, I try to ID all of what I have in the tank in the nearest future- I’m sorry for that


From the begging…
As some of you probably know, this tank is my first serious project and I did my research before setting it up. However, I couldn’t pass few mistakes and I learned new lessons… First, I’ve got too excited and ordered too many plant varieties and spent too much money on them. Second, I didn’t plan discus in my tank. I wanted a large fish and I thought about angels, but one day (about two weeks after filling the tank with water) I drove to the LFS and SAW THEM!!!! Price for my discus was a steal and I stared for a good 15 minutes at the tank where they were swimming thinking “They’re so beautiful- BUT I CAN”T TAKE THEM) Guess what happened? Did you ever have the same situation? Anyway, I keep my temp at 80-81F. I know it’s not the best for discus, but I am afraid of plants melting away. Discus are seems to be happy, though , they are active and eating whatever I throw into the tank
One more thing- this journal is a kind of retrospection, cause I don’t have enough time to be on-time So it all started in 06.17.09…

PAINTING THE REAR GLASS PANEL
I wanted black, permanent background so I painted my rear glass with rust-oil flat oil paint. I didn’t want to use spray paint because of the fumes, so instead I painted with foam roller. In order to get it done right, I did 5 very thin coats and it turned out good with nice and even surface.

MINERALIZED TOPSOIL PREPARATION
As I mentioned before, I’ve got my MTS from torpedobarb (thanks man). He suggested to mix it with some of the colorquartz and so I did. I bought a new mixing paddle and mixed rinsed CQ with MTS in the 5gal bucket.

I made a border of CQ and poured the mix in. That way I’ve got a 1-1.5” layer of mts-cq mix. I capped it with pure cq, but it turned out to be not enough so I needed to order some fluorite black sand to get that required 3” of substrate. I tried to move as much cq as I could to the back of the tank and them filled the empty space with pre-rinsed fluorite black sand.

HARDSCAPE
My hardscape consist of two manzanita “trees” made of Manzanita wood branches bought from Jake aka badcopnofishtank and few granite rocks collected locally that I used to hold Manzanita (I didn’t pre-soak it so it would float if not held by rocks). Here are some pictures of my creations- originally there were three “trees” that I’ve made, but I used only two of them in my setup.

I tried all methods of putting those branches together and from my experience, zip ties work best if placed in easy-to-hide spots. First I tried to screw them together with stainless steel screws, but it was PITA to do that, so I used J&B weld quick and glued them . It worked great at first, but after I put them in my tank they started to break at the seams (probably due to wood absorbing moisture, IDK). So I zip-tied branches together and it holds well so far.
So this was my harscape when there was no water in the tank.

I removed most of the stones from the tank after filling it ‘cause they took too much space IMO.

INITIAL SETUP AND FIRST THOUGHTS

So I filled my tank with water and to my surprise, the stand I built didn’t fell apart I purchased many plant packages I am having a hard time IDing now (I’ll try to shot a picture of every plant I am not sure of, maybe you’ll be able to help me IDing it) and started to cycle the tank. I’ve put two pioneers (guppys) into the tank to help establish a bacteria colony. I also used media from my old 2213 filter to shorten the wait time. I added my fisrt fish after 2 weeks and it might have been too early, but I haven’t notify any loss except one rummy-nose tetra that acted strangely from the beginning.
I made a list of observations I have made during the time that passed from the beginning of this setup that could help someone who is thinking of getting a tank similar to mine:
-open tank tops are great- I know there is a risk of fish jumping out (actually my killifish and both guppys that first appeared in the tank committed a suicide by jumping out), but hell it looks good You can view the tank from above and it’s so much easier to work around the aquarium. Evaporation is an issue as well (over a gallon per day here in hot and humit NYC conditions), but at least I am breathing with moisturized air in my apartment open tops really help with controlling heat in the tank, especially in hot summer days (however, a small fan is necessary to keep the temperature stable)
-Hydor In-line heater works very good and it’s very powerful, it keeps the temp rock stable, but sometimes it “fights” with fan during cooler days (I considered a double channel temperature controller, but it’s out of my pocket investment at the moment)
-Customflo vs eheim installation kits- at first, when I unpacked customflo system from the box I thought-“wow, so much customization options, it’s so great” but the truth is, you don’t need it- simple intake and spraybar work the best and take much less space in the tank that a “fancy” multi intake and a 90 degrees spraybar with weak flow; eheim installation kits are built with high-quality materials and are so much easier to setup and clean . Both customflo and eheim have caps on the intake and output sides that you can unscrew for easy priming the filter- smart
-eheim classic 2217 vs eheim professional II 2028- I have both of them working for almost two months and I can make a fair judgment of which one is a better filter- 2028 wins here without speculations. Cons are lack of quick-disconnects (but instead you have a disconnect lever on the filter body) and higher price, but there are many pros over a 2217. First of all, priming button on 2028 works great. I thought I won’t have to prime any of my filter more than once, but it’s not that easy. And when 2217 looses the prime, it’s one hell of a job to get it back to work again(updated, I found a way to prime this thing and it’s not that hard as I thought it was). Second, eheim installation kits simply destroy standard eheim classics intake and spraybar with their modular build, easiest of putting them together, priming caps, larger diameter of spraybar which allow to easier cleaning and nice grey-black color that compose nicely into the background (instead of that UGLY green classics use). Both filters are dead silent, so no winner here. And last thing, media baskets- maybe not necessary, maybe they affect water bypass, but they keep media organized well and make the cleaning process a piece of cake (almost)But In have to admitt, 2217 stuffed with media and filter floss means virtually no by-pass.
-two filters in a large tank is a great idea, you’ve got two inlets on both sides of the tank and two spraybars which help preventing “dead spots” In the tank. It’s convenient to clean one without turning off the other one. You can hook up an inline heater to one of them and DIY reactor to the other one. It’s safer in general- if one of them fails, there’s always a second one working; the only problem is more plumbing under your tank and more equipment in the tank
-3M colorquartz vs fluorite black vs fluorite black sand- since I couldn’t make a 3” layer of substrate with CQ I’ve had, I was forced to order some substrate material; I couldn’t find CQ locally, so I ordered two bags of fluorite black online- one regular and one sand variety; Fluorite black sand has very fine particles and it’s not pure black, more like very dark grey- I used it in the foreground to let foreground plants get their nutrients instantly, fluorite black looks just like crushed coal ore, it’s shiny black with blue hue here and there, has rather large and coarse particles comparing to CQ. I didn’t use it in this tank, I was a little bit worried of corys hurting themselves with it. My verdict is- CQ is the best substrate for the money when used as a cap for MTS; it’s the darker of those three, has perfect sized particles, holds slopes well and is cheaper than fluorite. On the other side, it’s hard to get locally, rinsing takes forever and it doesn’t have any nutrient content in it, but it still the best option for a MTS substrate cap IMO
-pressurized CO2- there’s not much to say here except that when you get one you’ll realize how DIY CO2 sucks No, really, co2 system with good regulator and metering valve is well worth the money you spend on it

FIRST TWO WEEKS

I’ve got some pictures of the tank after two weeks from the start of this setup.

Pics of my fish:

My German blue ram male- this guy along with his “wife” are my oldest fish by now and they were happy living in 15g tank before

One of my rummy-nose tetra school- those are really good scholers , they swim together almost all the time

One of my panda corys looking at the GSA on the glass- amazing fish as well, very active and form a school sometimes, especially at night or when the happen to meet in one place

Two of the three juvi discus I have in the tank. Aren’t they nice?

Madagascar rainbow male

Otto resting on a Manzanita branch
So that’s how it looked when I first planted and stocked the tank. I will keep you updated in the future!
Those two first weeks were mix of excitement and dissapointment. First impressions-wow, the tank gives me so many possibilities and is such an eye-catcher. I like the way it looks in my living room and it’s like a magnet- you keep staring at it even that you have to do other things Now I know why people are keeping those 200g tanks at home In aquarium hobby size defenitely matters
But then the algae came. I read that you can have initial algae outbreaks with mineralized soil, and it happened to me unfortuantely. First came brown algae, usual stuff in new tanks, but seriously, I haven’t seen anything like this in any of my recent planted or non-planted tanks. I had so much of oit that my ottos had bellys like santa claus . At least they were happy. I prunned all the moss I had in the tank and put it in my RCS tank. Shrimps took care of it everytime I was putting new portions
Now I am fighting traces of BGA and infection of BBA. Anyway, I really like to post it today, so I’ll keep you updated when I’ll find some time.

nice work man! i really can't wait to see it grow in some more. i wish i had the patience to write that much. subscribed.

 

[hydrophyte]

Nice job Marcin. Great tank, and great journaling. I need to read through it and digest. You put this on that excellent stand that you built right?

You have real nice fish in there they must make an excellent display.

Hey that list will be somewhat easier to follow if you use bullets. You can go back in and edti and add the "list" open & close tags then the asterisk in brackets at the beginning of each new line.

Man! That was a lot of writing indeed. That alone, takes a lot of time & dedication. I know you'll do great with this tank. Keep up the good work. I'll be following your progress.

That's a beautiful GBR. They only get that colorful as they fully mature. How old is that guy anyway?

 

[talontsiawd]

I love (and really hate) when people start better than what I put months into. Looks great and i love your selection of fish. I have been a plant first, fish second person and lately I want to get rid of fish but I had them for so long, I don't know what to do. Anyway, great start, looks like it will turn out very well.

 

[Postal Penguin]

Beautiful fish and tank. The ram looks stunning.

 

[nemosreef]

Great tank. Love the fish choices. Keep us updated.

 

[Strick]

I love it. Hardscape. Flora. Fauna. All of it.

Great job!!

 

[belladee]

I dont usually comment on tank journals but I think your tank, hardscape and flora are all absolutely beautiful. Enjoy it.

 

[Coltonorr]

Wow Great Job!
the tank looks awesome...super nice manzi too!

 

[randomrambler]

Very nice, I definitely could not tell that you were new to planted tanks by looking at it. And your stock list is almost exactly what I would choose if my mom wasn't stuffing the 55g with mollies lol.

 

[topfrog007]

I love your tank. GBR's and rummys are my two favorite fish! =)

 

[smoq]

First of all, thank you all for your comments and kind words. It really puts a smile on my face when I read them. The tank looks how it looks mainly thanks to you and this forum, I hardly knew what a planted tank is before I joined I'll try to keep you updated as often as I can.

Thanks man. Yes, I put the tank on my stand and it sure look good I mean, it didn't collapse at the first place and that was my biggest goal
I'll try to use bullets, but it seems to be a lot of work to edit that amount of text:flick:

I'm glad you like it. It took me many nights and many drinks to write that, especially when I needed to use a dictionary when I didn't know a word or two, but I like writing and publishing so it was fun.
My Blue Ram- well, who knows how old is he, when I got him about 1 1/2 years ago he was a 1" juvenile, so I guess he's about 2 years old.

I love (and really hate) when people start better than what I put months into. Looks great and i love your selection of fish. I have been a plant first, fish second person and lately I want to get rid of fish but I had them for so long, I don't know what to do. Anyway, great start, looks like it will turn out very well.

Tell me about it. I was so frustrated sometimes at my previous tank where I couldn't do anything good. But it comes with time and patience. When I saw algae in this tank I wanted to take this tank down, but then I said to myself that I have to be more patient and put more work into it. I hope it will be worth the effort.

Thanks again for all comments and feel free to ask questions and give advices

Update 08/26/09

I wanted to do a little update with more pics.
First, I forgot about the technical side of this tank, so here are some pictures of it.

Here you can see Eheim 2217 hooked up with PVC reactor. As I said before, I wasn’t very pleased with that filter at the beginning because of priming, but I found a good way to prime it (I simply sucked the outflow pipe before to get this thing working, that was so stupid of me). Well, what I do is unscrew the double tap connector on the outlet side until some water spill in the bucket and then screw it back together. That works great for me.

Second filter, Eheim Professional II 2028 and hydor in-line heater on the outlet pipe. And food on the first plane

I bought a LED light set to lit my stand and glued a switch to turn it on on the side. It really helps working with timers and stuff, but if I had to do it again, I would DIY the light myself- those leds from home depot are quite expensive and not bright enough IMO.

I also forgot to mention that I made a blue LED light strip myself to “pimp” my tank a little bit. It turns on after T5’s turn off and stays on for 2 hours. It doesn’t do anything good except looking sexy That second picture was shot at shutter speed of 30 seconds, it isn’t that bright in real.
Few shots of plants

Rotala sp. Green- one of the few plants I didn’t have any problems with- it took off right from the beginning and algae keep off from it magically

Lobelia cardinalis- no BBA here, but you can find some green spot algae here and there. I am still waiting for side shots.

Rotalas indica and rotundifolia- doing well, I hope they’ll stay that nice reddish color.
I’ll try to post more plant pictures in few days.
I added some livestock to the tank from invertzfactory as well

7 zebra nerites snails- great addition, they help with keeping the glass clean and they look great as well, don’t you think?

7 amanos- I always liked them and they’re big enough to survive with my fish. They are great at hiding, after a day of when I put them in the tank I thought they all disappeared but then one week later I saw 6 of them in one spot. They are among the best when it comes to algae-eating capabilities.

7 blue tetra (was 8 but one disappeared somewhere and has never been seen again)- I liked the vivid blue color of them when I saw pictures on the internet. Mine aren’t that blue, but maybe it comes with age, IDK
I also bought 3 assassin snails to control the snail population but I couldn’t find them at the photo session time.
So, what do you think about my fishstock? I am afraid I overstocked the tank already, I wanted to buy 2 SAE’s but now I think it could be too much. I’d like to hear your opinions
Few pictures of other fishes I mentioned before and I am going asleep

 

[CL]

Excellent job! I love the fish. The scape and stand look great to. I like where this tank is going.

Good write-up

 

[malaybiswas]

Love your tank, specially the driftwood and the ram

 

[fish dork]

I like it! Your female ram looks about ready to lay eggs.

 

[smoq]

I have a quick update, I forgot to write down my water parameters, so I checked them today and found confusing results:

Water temp: 80F (with +/- 1.5F changes during the day)
ph: 5.0-6.0 (here I have a problem, because the lowest color on chart is bright green and it means 6.0, but mine is more yellowish, like in drop checker)
kH- 2-3 (same problem, I tested it twice and the first time the color didn't change from blue to yellow at all, it was yellow after the first drop of reagent; second measurement showed yellow after 3 drops)
NO2- <0.3 mg/l
NH3- 0mg/l

Question is- should I be concerned about that low ph? My drop checker was yellow today after playing with metering valve last evening and my fish seemed to be less active so I reduced the flow of CO2 today and it's back to bright green. Weird thing is that when the drop checker is yellow I see a lot of pearling, but my fish act strange while with bright green I see almost no pearling except for blyxa but my fish swim happily.
The solenoid turns on two hours before the light and turns off one hour before the lights. First two hours after the lights turn on drop checker is dark green, then turns bright green the next hour. Is it normal?
Thanks for all your answers.

Update with more pics of plants.

Foreground confusion

Echinodorus tenellus "micro" kicked back very quickly and that was a nice surprise. It has a nice red hue due to high light but some BBA is attacking it

Dwarf sag, grows like a weed. Nice bright-green color and stay low in my tank. Nice plant to those who want to have a nice carpet quickly.

Dwarf hairgrass -Eleocharis parvula in the front with stargrass in the back. I didn't like hairgrass at first, but know it looks so nice, however, it's a debris magnet.

I am really confused right now- I don't know what to do with my foreground. I was thinking about getting rid of dwarf sag and do echinodorus tenellus and stargrass foreground, but I also had a little patch of HC left (the rest died as usual for me) which I was preety sure it would die, but it kicked back and now staring to grow. What should I do? Any reccomendations?

Pennywort was a plant I always wanted to have. It grows very quickly and I don't know if it wouldn't be a PITA to trim in the future

Macaya fluviatilis- absolutely amazing plant with fine leaves, I am trying to make a nice bush out of it.

Lobelia cardinalis- grows nicely, but it's time to trim and I don't know what should I do with the bottom and how it will look after trim.

Any comments and advices about where should I go with the scape will be very appreciated Right now my tank is rather a plant farm than a properly scaped aquarium and I am trying to figure out which plants will do well for my scape.
One last thing- what do you think I should do with that low pH? Thanks guys, I will keep you updated...

 

[hydrophyte]

Hey this is great. I think we hadn't seen this one in a while. Your plants are beautiful.
