Hey Tony....I am assuming that you have this on your system? Is it a good idea to have one on a reef tank? I am confused by the UV/Ozone talk and I have never had anyone say that it was the thing to have. But if it does improve water clarity I am always interested. Thanks in advance. B

For the most part UV will make a difference for water clarity as it helps break down the compounds which tend to make the water yellow (similar to ozone). For pathogenic control purposes such as for ich control you need a large UV. For example, 50w or up. The smaller units like 8w or 15w or in that ballpark are intended for clarifying water more so than pathogenic control.
