thanks for the replys. Ok i have had my reef set up since jan 1, i have 26 lbs of live rock, 7 hermit crabs four turbo snails a tiger stripe brittle star for the clean up crew. i have about 2 inches of sand too. my lights are the same age and are for a reef setup. i clean everything once a week except for the protein skimmer. i appreciate the help, i love having a reef tank. and when it is looking good it is so worth it
. thanks again and i hope everyone has some ideas on my problem.
