I have a 45 gallon hex tank that was started about 6 years ago, with salt water fish, but have been really excited about making it a reef tank. I have approximately 30 different corals in the tank, and am very fussy about the water being crystal clear, and do water changes every week to keep it that way. I have been looking into getting a UV sterlizer or a carbon reactor, and wanted some thoughts on which would be the better choice, if I can’t go with both. I currently have an Oceanic tank with a wooden stand below, that houses a canister filter. Any suggestions would be greatly appreciated.
