My tank has went crazy with brown algae the last few days , it's a 55 gal planted tank with 4---48" t8 6500k lights . I leave the lights on for most the day , prob about 13-15 hrs . Any ideas
I haven't been running the light as much and it seems to slow down and some turn green
Sounds like time for blackout and WC
or get some bristlenose plecos...
