My tank is about 6 weeks old now, and I have some nice brown algae on the glass and LR. THe cleaners are doing a pretty good job with it, but I remember someone on here telling me to add some macroalgae to help out. I really don't want something that will overrun my tank, so what kinds are very beneficial AND also easy to control? I really don't have any fish that would feed on it, so control is the big issue, and also a refugium is no where in my budget right now so forget that....
