looking for some info i just set up my new 450 gallon tank. For filtration i have one sump wet dry and 2 FX5 filters at first i thought heating the tank would be a problem so i put two of the best heaters in the sump and in a surprizing 2 days the tempature rose to 84 degrees and now i turned off both heaters and it wont drop a bit it seems like the mag drive 3600 pump is giving off a lot of heat and is very loud im not fermilar with this pump is this typical? Any suggestions would be greatly appreciated.
