My wife and I started to cycle the new tank last weekend with live rock and sand only. Initially we had some problems with high temperatures. Every thing is new. After turning the heater down from 78 to 72 degrees the tank was 78.6 this morning at 0630, the lights come on at 1200, it's 4:00 now ( halfway through the light cycle) and temp is 79.3. (JBJ CF
Lighting) Last night at 900 PM it was 79.0.
I have a few questions.....is that two much of a fluctuation for coral? (we're planning to go there after cycling is complete, a month or more.) If so do I need a chiller? IF I need a chiller where can I find one for a nano, and approx. how much?
