Tank size: 26 gallons
Plants: java moss, anubias, val nana, bolbitis, moss ball, s. repens
Filter: Eheim ecco pro 130
Pressurized CO2: 2bps
Fish/Inverts: 20x galaxy rasbora, 10x young albino cory, 2x bnp, 40+cherry shrimps, 3-5 nerites, 1 SAE
Lighting: Finnex planted 30"
Nitrite: 0 ppm
Info: Only have bba around the filter output area where water comes out. The output spraybar does not have BBA EXCEPT right where the water comes out from the spraybar. I thought BBA occur from fluctuation of CO2 or not enough water flow but it seems to love where the water flows the most. My CO2 is running 8 hours a day on solenoid and timer. The BBA is nowhere but where the spraybar water output holes are and on the edge of val nana and leaf of bolbitis right where water shoots out. Any ideas?
**In these photos I have sprayed H2O2 on them so they still have bubbles and is reddish. Is will most likely be a temporary solution but I want a permanent solution. Thanks!
