BBA..The worst enemy...ever..

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"
PH: 6.5
GH: 5
TDS: 155
Nitrite: 0 ppm
Nitrate: 10ppm
Ammonia: 0ppm

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!

Kill it (you're already on top of that part) then try to reduce lighting and/or get more plants that can out-compete it. Also make sure that your tank is nice and clean. I get BBA when I remove a lot of plants at once, have a dirty tank, etc...

IMO it is a complete myth that BBA goes away when you up CO2. I have never once seen this work.

Once you kill it and your plants can out-compete it then it will go away. I still get some on my hardware in places (pipes, rocks, and powerheads a little bit) but when it grows on your plants then it is a real issue IMO. Only algae that I can never 100% get rid of. Just manage it to the point where it is barely present then accept that as a success. As long as it stays off your plants and can be managed then you're all set IMO.
