FYI, tried a MAG 18 in my 45g. Heated to 88F in 3 days from cold tap water. Way to much heat. I am now running a Pentair Quiet one 3000 for closed loop(pump is in Overflow) and a Mag3.5 in the Sump. just fine.
a mag 18 is alot larger bodied pump than the 7,9,or 12 that I recommended, and transfers alot more heat, and is very noisy compared to the smaller mag drive series.
