Well, I'm out of possibilities then. I still dont believe its the mithraxaznfish;4781948; said:the guy had the live rock for years, the tank had been setup for atleast 3 years.
I didn't add any live rock into the setup.
note, i did move most of the live rock from a 180g into a standard 3 foot, because i am doing adjustments to the 180g and its 65g sump.
there is also live rock in big buckets of water, but i don't here clicking from them.
