I have a 55g cichlid tank I've had up and running for about 8 months now. I have about 25 various cichlids in it mostly african with 3 bachardi. Two questions I would like advice on. I am in a constant battle with brown algea. We do a 10% water change weekly and all the parameters are good. we have two Emperor HOB filters (one double and one single) and have changed the filters just a week ago. We have reduced feedings and amount of light time. What can I add to help get rid of the brown algea or at least keep it tolerable? We haven't added anything new to the tank in quite a while. Also what can we do about the murky or hazy water? It isn't bad but it when from being crystal clear to hazy in the last month or so and I haven't been able to get it clear again. We use RO water instead of tap water. Help/Advice please.
