Heater Size for 150G w/ 70G Sump?

[Robg719]

I have (2) Eheim Jager 200w heaters. My tank is 150G w/ a 70G sump... will that be enough to maintain the right heat levels?

I have one 300w on my 72g and a 150w for my 29g which work well. So I would probably suggest (2) 300w+. Just my 2 cents, I'm sure others have better knowledge for that size tank.

Two 150w heaters in my 75g (73g actual volume with sump) are able to keep my tank approximately 13°-15° over ambient in the winter which works out OK as I keep the house right around 65° at night. Depending on your location (i.e. weather) and volume of water, you'd likely need at least double that.

Thanks. I spoke to someone at BRS and they recommended 2 300's, so exchanging them
