Do you mean am I feeding enough? I don't have a very high bioload at the moment. It's 70 gallon system with only 2 clown fish and small blue tang. I feed once a day - a variation of frozen brine and probiotic pellets.Do you have high enough nutrients to support the algae?
People use sandpaper to rough it up in hopes that algae would grab on easier.What should I use to rough it up?
