Try increasing the water circulation within the tank first.
I have two powerheads, a nano 400 and a 240. The co2 atomizer is under the 400 which is in the back corner. The 240 is on the other side, in the front corner to return water to the other side. I don't know how it could be anything other than a placement issue with those powerheads in such a small tank. Do I need to change their locations? I've tried two other configurations with no luck on that, either.Definitely sounds like you need to improve circulation within the water column.
There's iron in the substrate and iron in the micros as part of EI. I don't separately dose for iron, though.Do you dose for iron?
What kind of micro do you dose? Not all of them include iron.There's iron in the substrate and iron in the micros as part of EI. I don't separately dose for iron, though.
Flourish. I don't see how iron could possibly be a problem, though, with it being dosed and in the substrate. None of my plants show any signs of iron deficiency.What kind of micro do you dose? Not all of them include iron.
If it's flourish "micro", it contains no iron. Flourish comprehensive does, though. And lack of red could be an iron deficiency.Flourish. I don't see how iron could possibly be a problem, though, with it being dosed and in the substrate. None of my plants show any signs of iron deficiency.
It's comprehensive. I know what I'm dosing And yes, it could be a sign of iron deficiency, but I just don't see how that's possible. 25% of the substrate is clay powder. I'll dose iron if I have to, but it seems like there are other areas to improve that are more likely to solve the issue, especially considering the BBA.If it's flourish "micro", it contains no iron.

I've tried different photoperiods, but nothing seemed to have an effect on the algae nor the plant coloration. Right now, I've settled on a 6 hour photoperiod.You may try to Lower the light intensity by raising the fixtures or shortening the photoperiod. That should lessen the need for so much co2.
Only change that and observe for 2 weeks at least.
Well.... I think that could help.
Question: were the plants brighter red before and now are more flat?
They are in the center. 39w per bulb. It's a 4x39w 36" T5HO, which is why only two bulbs are on at any given time. So, really, it's just 2x39w for 6 hours per day. Having all the bulbs on, regardless of photoperiod, only contributed to green spot algae and had no effect on the coloration of the plants.are red plants at corner or center? and your T5HO are 24watt per bulb, am I right?
I tried that photoperiod and just got algae explosions.I had the red plants same as yours in my old tank(29G), and the light was 96 watt PC for 10 hours, noon time 96X2 watt for 2 hours. light fixture 6-8 inches above the water, the red plants were all red.
The temperature of the water was 75-77 degree.
