Help on 72 Bowfront

I need some adviceÖ I am new to the aquarium hobby since November.

I have 2 aquariums;

1. A 40g breeder @ my office with (2) Oscars and (1) bristlenose. This tank is moderately planted, with a couple Amazon Swords, a couple anubius, a few java ferns and several crypts. No C02, generic LED lighting, aquaclear 50 HOB. Fertilizing with Seachem Flourish
2. A 72g Bowfront Community @ my home; 2 Angels, 8 neons tetras, 9 corys, bristlenose, 1 reticulated hillstream, 2 german blue rams, 2 dwarf petricola, 4 otoís & 4 nerite snails. Plants are 3 large amazon swords, green cabomba, 4 crypt spiralis, 1 anubius, 1 dwarf aquarium lily, 3 dwarf sag, 1 val, scarlet temple, couple tufts of monte carlo. This tank has injected C02 thru a reactor, Eheim Canister, Finnex Planted+ 24/7 HLC Aquarium LED Light. Fertilizing with Aquarium Coop Easy Green & Easy Iron. Originally I was using DIY root tabs with Osmocote and have since switched to Aquarium Coop Easy root tabs. Also have crushed coral in the canister.

Both tanks have gravel substrate

The Oscar tank plants are growing well, very little if any algae, overall easy.

I need suggestions and how to get my 72 back on track.This tank started out with the plants growing well, then they sort of stagnated with the cabomba starting to get stem rot and the fans have an almost what I would call a filling layer of algae making a fan like a solid leaf if that makes sense. This algae is easy to remove if you rub the fan between your fingers, this is on like 25% of the fans. The swords were growing well, sending out runners with baby plants etc. then started forming fuzzy green algae, on some, but not all of the leaves. Not sure of the type of this algae, but it is very difficult to rub off. The lily used to send lily pads daily almost to the surface, hasnít done this in over a month. The leaves off the bulb are all staying lower in the tank and also prone to melting/rotting off.

I also havenít been able to get the plants to pearl which is troubling. I have the Co2 at roughly 4bps and have a good green color on the drop checker.

My current water params are stable with;

PH - 6.8
Ammonia - 0
Nitrites - 0
Nitrates - 10
KH - 6

Any help & advice would be immensely appreciated!

GH?
Phosphates?
Lighting schedule and intensity?
Water change amounts and frequency?
Dosing amounts and frequency?
GPH of filter?

Sounds like bluegreen slime algae (Cyanobacteria) on cabomba leaves?

Thanks DaveKS for your quick response...

Not sure on the GH or phosphates as I don't have a test kit for either of those, but can certainly get one...

I use the standard 24/7 program on the Finnex light, although I was wondering about that as it is only completely dark from midnight till 6am.

I perform 35%-40% water changes weekly, after which I dose 7 squirts of both Easy Green and Easy Iron.

Not sure of the GPH, the filter is an Eheim Professional II

This was a tank that was used by a friend back in the 2005ish timeframe for a few years and has sat ever since. I upgraded the light and a few things...

also looking at pics of Cyanobacteria, I don't think that is what is on the cabomba. It doesn't have that foggy/cloudy presence, it is just a coating on the fans, and it is pretty dark greenish. As far as the water is concerned it is crystal clear.

Why are you dosing so much easy green/iron?

Easy green
Medium-High Light
1 Pump per 10 gallons twice a week.

Easy iron
Dose 1 pump per 10 gallons.

Iron should be dosed on days between easy green doses. Easy green you need 2 pumps twice a week, maybe 3x week if uptake is high. Once a week dump and run dosing is probably cause of your algae.

being a 72g, so I am dosing 7 pumps of each per week after the water change. I thought about doing a second dose easy green like 3 or 4 days after the water change but was worried this may fuel the algae even more... saying that iron should be dosed between easy green doses, is there a reason to not do them at the same time?

Thx

No help on the algae but curious what temperature you keep the tank. Hillstream loaches are usually recommended to be kept below 75 deg, German rams above 80.

Sorry I don’t know why but I was thinking a 20gal aquarium. DUH


Easy green already has the dose of iron needed. Iron is to dose in between that dose to keep iron levels up, it’s a quickly depleted Micro in tank.

Noted, thx for the info on the iron... mainly dosing the iron to bring out the reds in the dwarf lily and the scarlet temple...

That light should be providing around 40ish ppfd at substrate which should be fine for your plants. Which canister filter are using exactly? A picture of the tank is always very helpful. By any chance is your algae on the lower leaves of your cabomba? A lot of plants need to adjust to new water conditions when moved from one location to another (like from the store to your house). I find that the easiest solution is to cut the top few inches off a stem, discard the base and replant the tops. Tends to work pretty well. You may also just need more plants for the water mass. And 4 bps in a 72 gallon tank is pretty low. You could raise that up to 7 or 8 and see if you get better results.

Also be aware that those oscars are probably not going to be ok in the same tank for much longer. Likely your oscars are juveniles and thus have not gotten their aggression up to full levels yet, but as they grow that 40 gallon is going to be WAY too small for 2 of them and one will eventually kill the other.

Ditto.
The OP didn't ask a question about his fish/stocking so I didn't say anything yesterday when I first saw this post-- but, yeah, disaster waiting to happen.

I know, and chalk it up to ignorance, but also my LFS knew what size tank they were going into and didn't discourage

I would have separated them by now, but they are literally the best buds. Snuggling while sleeping, constantly brushing against each other, really affectionately. I just don't have the heart to split them up until necessary, realizing it 100% will be necessary at some point. Currently the larger of the 2 is approx 5", at that point I'll donate 1 or both back to the fish store.

Getting this post rolling again...

I've attached an overall view of my 72g community tank as well as some close ups of the algae on the plant leavesClick image for larger version

ID:	898217 that I would like to control better. I need help identifying the type of algae that it is as well as what I might try to combat it. Here is what my current routine is...

1. 40% water change weekly
2. Easy green, 7 squirts, 1x week after WC.
3. Easy iron, 7 squirts, 1x week after WC.
4. Latest water parameters: PH=6.8, A=0, Nitrites=0, Nitrates=7.5, Kh=6
5. Lighting=Finnex planted+ HLC running custom program lights off for 12 hrs, ramping from noon to 3pm, full from 3 to 9pm, ramping down to dark @ midnight.
6. C02 injection through reactor from 1pm to 9pm
7. Air pump thru 2 air stones at opposite ends of tank from 10pm thru 1am.

Any help would be appreciated, thanks.
