Hey everyone, i am very new to the hobby. I have read every piece of literature i have been able to get my hands on about marine fish and reef keeping, but I still have a bunch of questions. I recently set up my first salt water tank. It is a 75 gallon, with about 60lbs of live rock and a few fish. I am having problems controlling the temperature of my water and have tried everything from raising my light off of the tank, changing the heater (incase the thermostat was malfunctioning), and I have checked all the mechanical devices to make sure nothing has clogged and overheated. If anyone has any ideas to help me control the temperature of my tank I would appreciate some advice. Thanks.
