Ok, heres my question, my 55 gallon is running for about 4 months now, i have some cleaners in there , shrimp, snails, crabs, and my tang really cleans my rock and picks at the coral on the bottom, but, ive noticed it starting to get browner, should i just vac it up? or change to sand? and if i change to sand, how do i do it with a cycled tank and all the inhabitants in there now? some good advice would be helpful here!!!
