Ok ive read up on this but cant seem to get a straight answer on what exactly to do to get rid of it completely. I have a 65 gal tank 36x18x24 with 3x39 w of t5ho, dosing ei for a 40-60 gal tank, rena xp3 filter and pressurized co2 with a rex rigg reactor. I have been having algae problems since the beginning. First i had green water so i bought a uv. then i got blue green algae so 3 day blackout +EM. now i have bba. My co2 is at least 30 ppm using 4dkh water in drop checker and just on the yellow side. I have the lights on for 8 hrs per day. anyway what should i do to get rid of the algae. i have been trimming and cleaning but its spreading faster. this mainly grows on my dwarf hairgrass, microsword, and java fern.
