my 20g tank has been having problems with excessive brown algae, i have taken the tank out of the sun and this has stopped my green algae, could there be a problem with phosphates?? any recomendations???
I am having onging problems with one of my nano 24's. Brwon algae covering everything along with lots of reddish algae. Many water changes and using natural sea water with light on only 8-10 hours. Going to pull it down,clean rocks and start over.
