I think its BBA? Its black & greenish, thready, on all my live plants.
I have a 55W PC, PH is 7.6 - 8.0 and KH is 120ppm, Nitrates are 20PPM and Phosphates (no test, sorry). I can't add any fish right now as I am battling some disease thats slowly decimating my Tiger Barbs otherwise I woul start with Rosy Barbs.
I read raising the temp to 84 - 86 might help, will this be OK with the fish? Tiger Barbs, Cories and Clown Plecos?
Thanks
