ok, so this winter here in texas looks like it's gonna suck, i need a CHE for both my tanks. this has to be a 1 shot thing if i order them online, im not sure what wattage to get, they both have 40g breeder tanks and i have dome fixtures with dimmer switches. right now i have just been wrapping them up in blankets and covering the tanks with sheets in hopes to keep the ambient air warm. but i need something better.. . . . help a broke guy out.
You think texas winters suck, try living in the north. Its 34° right now lol. If you have dimmers, get 150w and then you can adjust the temps. Better to do that then not have enough wattage. http://www.petmountain.com has good prices.
