Heaters for new tank

[pastelball]

I am setting up a 34 gallon DB frag tank with a 20 gallon sump. I have narrowed it down to the Eheim Jager TruTemp. Should I go with 2 of the 26-40 gallons 100W 12.2" or 2 of there 40-53 gallons 125W 12.2". I will have the apex for back up on temp control.

I use two heaters on my 90 as a failsafe in case one craps out at least you are protected some. You would probably be good with one on that size of a tank along with the Apex controlling it and monitoring temp.

Cool thanks. Going to place a order.
