Except for afternoon microbubbles from the O2 the macroalgae makes in our tank, our water is always clear. Mixed soft, lps, sps, bta BB 120g, low bioload, don't overfeed. No skimmer, no sump, no ozone, no carbon. 2 x 175w MH with PC actinics. Weekly maintenance, 15% water change, lots of crud siphoned from the bottom, too. I don't understand why folks' water isn't clear?
