Hello, I am new to this forum and I would like to start by saying that I have seen some beautiful tanks in here in the last few days that I have been on here . Great source for anyone in this hobby .I am having a bit of a problem I have had tanks for years up to 100 gallon never done a reef in a 12 g my problem is heat what is the normal temp for these tanks I mean with my larger tanks 79-80 was no prob but with this tank I am hittin 81-84 f which is in some peoples opinion ok in others its bad what is you guys opinion on this .my heater is 200 watt and I have it set at 76 degrees it never has to come on the tank is always in higher temp more so when the pc 's are on thx .

Raise your heater to 81, temp fluctuations at night are a bad thing
