BBA Solution ?

I've been battling BBA for awhile now in my standard 29g. Running 2 T5HO bulbs (not sure on the wattage) for 10 hours a day. Dosing root medic daily. Pressurized CO2 is running at about 3-4 BPS (enough to keep the drop checker yellowish green). I just double dosed excel and will do a 50% WC in a week (hoping this cures it). Tank is heavily planted and the plants are all growing well and look extremely healthy. I don't want to turn up the CO2 and risk gassing my Oto population. Any other solutions I'm missing ?

I am prepared to meet my Maker. Whether my Maker is prepared for the great ordeal of meeting me is another matter.

Lower lights...raise co2. I'd look at hollies chart for par results for.lights. it seems you have way to much light.

Turn off your filters then directly squirt excel on to any and all BBA you can find. Wait for a minute or two then turn your filters back on.

The BBA will turn out red/purple in a day or two and will die off. If the BBA returns, it means you still don't have enough CO2 for the amount of light you're using.

As for otos, I'm pretty sure they can handle high amounts of CO2 as long as the plants are photosynthesizing well and producing high amounts of O2. In my tank, the pH drops all the way down to 5.7 when CO2 is injected (and controlled by pH controller). If I put aside tank water and let it de-gas for 48+ hours, the pH is at 7.0. If you go by the CO2=3*10^(pH drop) formula, it calculates to 59.8ppm. That's basically double the 30ppm normally preached.
