48" rimless iwagumi

Hello everyone,

This is my first real planted tank aside from tampering in tiny tanks to learn the ropes. The tank is 48"x15"x15" with 1/2" thick glass. The rest of the specs are as follows:

Filter: Eheim 2028
Lighting: TEK 2x54w T5HO 6500k
Heater: Hydor 200w inline
Substrate: ADA Amazonia II (32L)
Hardscape: Zebra Rock (~80lbs)
CO2: 5lb canister w/ JBJ Regulator and 1.37" diffuser at 3 bps
Flora: HC with Glossotigma as a accent around large rock periphery. The back wall has Dwarf MicroSword.

The tank has two mounds where the angular rocks jut outward. The left is a bit higher. The middle of the tank is the low point, as well as the front of the tank. It creates a sort of river delta or valley. The front substrate is about 2" deep and the rear is at about 3.5"-4" deep, although the angle of the photos don't really do it justice.

I will plan to add livestock VERY soon as the cycling is nearing its end...

**The stems are not going to be in there long term. Nor is the second CO2 diffuser on the back wall; they are just placed for assistance until the 20 gallon rimless goes active. I also have 17mm lily pipes and clear tubing just waiting for me to put them on...

Is this the same tank that is in your other thread? It looks great. I would suggest adjusting the spraybar to make less surface agitation so that your co2 stays inside your water

Thanks, I didn't think of that. I'll fix the spray bar tomorrow or just put my lily pipe on. Yes, it is the same tank, just rescaped a tiny bit (changed a few rocks out for others and shrunk two via chiseling) from the aquascaping thread. Just figured it was time to move it here...

Blair,
Tank is looking good! I agree that's it will be awesome one the carpet fills in...

Are you planning on taking it with you when you relocate?

impressive. those rocks must weigh a ton. i wish that the big one in the left foreground were positioned in a little bit more to the right, but that's just me.

this will look great with the carpet.

Thanks everyone! The growth is starting to explode... at least for the glosso but the HC is only slowly making a gain. The stems I put in there are also growing nicely and sending off root shoots all over. My new Aqua Soil Amazonia arrived today for my 60-P knock-off and I will remove them after the cycle is done for this new tank.

I decided to bring over 5 gallons of established tank water to continue to help it cycle a bit more. All of the 'coco puffs' from my eheim 2213 were put in the 2028 (only filled half a tray) to also give it a bacteria boost. Sadly, it continues to read a solid 1 ppm ammonia. Hopefully it cycles soon!





The water is super clear now

Tank has some new citizens. I purchased some stellar shrimp from kangshiang. I now have 15 S to SS Crystal Red Shrimp and 15 S to SS Crytstal Black Shrimp I'll post some photos soon. Oh, and it now has 3 Otos.

Arriving later this week are 50 Neon Green Tetras from Invertz Factory.

I am having a bit of trouble with green string algae of all things... It is clinging to my HC in the middle of the tank, very low growing and nearly impossible to remove. I have been stopping my filter for 15 minutes a day, targeting the patch with excel, and then starting it back up a few minutes after I let that sink on top of it. I have been trying to keep the dose of excel at what would be recommended daily... but I am not sure if I can safely increase it a bit to combat this pest ?

Thanks for all the kind words. And yes, this tank and my other two (20 and 25 gallon rimless, starting ASAP) will be going to U of M this fall with me for grad school. My tiny studio apartment will pretty much be wall to wall water

I'm looking forward to the new pics of your tank growth and especially the green neon tetras. Can you let me know how well they school in your tank and if you have any jumpers?

I'd be careful with how much Excel you overdose. I think roybot73 recently killed off most of the fish in his 60-P this way.

Looks good over all. Just some minor thoughts/constructive criticism: I think the Iwagumi concept is very much based on an almost Zen-like almost severe simplicity and a careful "balance" of the elements used. I think you have a few too many rocks and in a much too haphazard placement to really be called an "Iwagumi". If by Iwagumi you simnply mean simple and less cluttered vs. a big ol' stem-filled planted tank then you do have that. Personally I'd prefer to see less rocks and see them more to one side than the other. It would be more "harmonious"!

Just some thoughts. You can tell me to go to hell if you want....

The algae can easily be controlled by a 3 day blackout and then adjust that CO2. Maybe 2x a week, 1/3 to 1/2 the water changed.

Too many rocks for the idea and essence, nice tank size!

Rich815 - You make a great point. I have been trying to figure out what needs to be removed and I think the idea of one preferential side is much better. I will need to consider how to do it and keep the odd ratio and groupings. I now have 32 shrimp roaming around that need to be considered as well when I tackle it.

All my tanks will be torn down in 3 months time anyways for a rescape when I move, but I'd love to handle this sooner...

Tom - Thanks for the suggestion. I will do the blackout ASAP. I agree about the rocks.

Is there an area to look at examples in the iwagumi niche? I know Creative Aquascape Union has some great tanks, but they are more often driftwood based... very few purely rock scapes. Any pointers for where to look?

Tank looks nice.

I know in the past I googled "Japanese rock garden arrangement rules" or something to that extent and came up with some good information.

I like the rock!

I really like this setup, but I agree with the others that you could stand to lose a few rocks. I like the idea of having the focal point more on one side, I would lose all the large rocks on the right. as for the algae, with all that light you really need to have the co2 cranked. a shorter photoperiod would probably help a lot. A blackout will get rid of the algae, but it will come back quick if the problem is still there. I would try to get the algae under control first. and try a google image search for iwagumi. lots of awesome pic's

I know enough to know that I don't know anything
