So I'm trying to get my tank cleaned up. What is the best way to get my water crystal clear. My skimmer is working great, sump with refugium seem ok no chaeto. I have a pre filter in the over flow and water tests are great water changes every 2 weeks. Just seems like there is always debris floating around in the tank. I see all these pictures of tanks and the water is beautiful. Would charcoal help or maybe a uv sterilizer? Any suggestions.
