Problem: Tank not getting up to temperature. Its a 100g tank, with a 20g sump. I bought 2 eheim jager 125w heaters, both are in the sump. Site says they'r rated for aquariums up to 53g. They are both controlled by a RKL. Temp won't go above 72.
My guess - not enough power. The next size up is 13 inches. After hanging out with my buddy Pythagoras all morning, the longest heater I can fit in my sump would be approximately 13 inches, maybe 14 but that's pushing it.
Option A: order shorter, but possibly less reliable heaters.
Option B: rebuild current sump, (20gL) to make return section smaller 1 longer heater would fit in the fuge section.
Option C: Buy a new, larger aquarium for sump and rebuild while tank is cycling.
Option D: Buy a ready-made sump so I don't have to deal with it.
Opinions? Other options?
