Need a Heater Recommendation

[goisles1]

Can someone recommend a Good heater for my 45G Tank with a 20G Sump/Fuge?

Right now I have a 150W heater down in the Return area of the Sump and my temps are dropping too much during the night. and It's only Fall.. When I checked the tank this morning, it was at 76.5 degrees. Yesterday, It took a few hours to get the tank back up to 80.

It appears my small heater cannot keep the temps stable.

Thanks,
Rob

I'd just put another of whatever you already have in there (a duplicate of the 150W one) and call it good. I have 2x 100W heaters in my 46g (no sump), so 2x 150W in your setup doesn't seem out of line.

That makes sense Kurt.
