i have algae in my aquarium on my rocks and sometimes it gets on the glass. it is moss like i guess you could say it looks kinda fury. i dont leave the light on but about 8 hours a day so its not that because i used to leave it on for about 10 - 12 hours and there was no algae. i was wondering would i should do to try to get rid of it or is it normal. i have seen that they sell algae remover should i use that or does it have bad side effects. i have seen that there is an all organic algae remover would that be better?
