Hello There, I've been a keen fish keeper for a few years now and are still learning. I have a little black brush algae which I have now got saimese flying foxes taking care of that, however recently at the LFS I was told I've got the Algae because I'm having my light on for too long. Usually I have it on for 13 hours, the LFS suggest 4-6hours is enough! I've since tried this and it has decreased a little, but I don't see the point in having the tank if I cannot enjoy it! Because I cannot see the fish!!! Well that's all I can think of for now - when the pressures on the mind goes blank! Bye Mad Fish - not their owner??
