new tank? probably diatom...it will go away naturally, or you can get a clean up crewMy 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
Sounds like time for blackout and WCI haven't been running the light as much and it seems to slow down and some turn green
Yup YupSounds like time for blackout and WC
+1 or maybe a kissing gourami (cleared most algae on my planted 30g within 2 days)or get some bristlenose plecos...
