Heating help needed

[Big K]

Hello fellow Wetarms!

I have a 55 gallon reef tank with a 40 gallon sump (in my basement) and am having issues regulating the temp. I have three 150w Cobalt Aquatics heaters in the sump in three different areas. The temp fluctuates up to five degrees when all three are set at 80.

I am adding a 110 gallon FOWLR and a 20 gallon frag tank soon, so what will I need to do to keep the system steady? Do I need to insulate the lines going up/down?

So....200 views and NOTHING?

I would say your heaters are small for 90 gallons. I use a 300 watt and a 150 watt. 5 degrees is alot.

you should put the heaters in 1 area.

I would also get your temp down to 77 and 78 degree range. Slows down the metabolism of the bacteria and less chance your fish get an infection.

I would look into getting a temperature controller of some sort. I don't trust any heaters. Tolerances are too big for me.

I built my own controller a long time ago to control my heater and my fans. My temp never fluctuates more than +/- 1 degree or less.
