I know this has been asked many times, but I keep getting different answers from everywhere. What is the best temp range for my tanks. Tank 1 is a 55 reef with a kenya tree or 5, a lot of mushroom rock, button polys, corral bandaed shrimp multiple hermits a purple tang a sixline, a coral beauty, whatchman goby, and a mistake fish (malcor niger) will be removing when grows to big.

Tank 2 is a 14 biocube reef with a tomato clown a lawnmower blennie a scotter blenie a clown gobie anneome crab, multiple hermits of diff spec some mushrooms a huge blasto.

I keep my between 80 and 81. In Eric Borneman's Coral book he recommends between 80 and 84.

I use a controller and have it set so the heater comes on at 79 and the fan at 82. I used to have the chiller come on at 82 but since I got my Solaris I haven't needed it. The fan comes on occasionally when the house gets hot.

i keep my system between 78 and 80 degrees. my fans run when the halides come on until they go off. i am saving money to buy a controller so they do not have to run all the time, but with then running like they are ... i have less than 1 degree variation between no lights and all lights.

IMO 80-81 is perfect. I use fans in the summer when MH are on. But can't right now or it goes down to 78, so instead is is sometimes over 82. I would like to get a controller sometime to more precisely control my heaters and fans for prefectly maintained temperature.

Thank you all for your input. Guess I've been running a tad hot, around 83. I'll be cutting it back to 81 and see if theres a difference.
