I recently got back into the salt water hobby after selling my previous aquarium earlier this year. I decided to go a little bit bigger than what I had before (90 gallon). My current aquarium is a 180 gallon with a 75 gallon sump at the bottom, with roughly 140lbs of live rock (already cycled) in it. In the 180 I have about 120lbs of Carib seal live sand in it; with a huge piece of live rock and a 10" panther grouper for cycling purposes. My the only thing that I have not done yet that I would like to do is a good uv
sterilizer any suggestions?
