Thinking out loud here, my main tank (90 gallons) is in the basement. I work mostly out of my study and was contemplating setting up a 10-30 gallon tank there. Temperature remains a pretty constant 75-77. If I take some live rock from my main tank, some water and new sand ... just do lps and zoa/shrooms with 2-3 small fish would I need any filtration at all? No heater, no filtration just lights and a powerhead for movement. Yay or nay?
