I have been considering starting a chaeto refugium in my new system. I had one in the past that lasted only a few weeks before I had to tear down the whole system. So I just dont have much knowledge of what good refugiums can do. I just dont know If it's worth the hassle to grow chaeto or other macroalgaes, but maybe others have had real beneficial results with doing it. I have an extra chamber in my system that world work great for one, but am worried if I do end up growing chaeto, it wont do much for my tank. Could anyone chime in and tell me their experience with refugiums? Is it worth it??
