Using dual heaters - issues

[Bud8Fan]

I just bought a 125gal with a 1000 watt heater is that too big ? It seems to work okay but I don't need any fried fish.

Best heater calculator on the net. Just remember that it give you "minimum" wattage. Round up.

Nice link bud, to get my 75g 10 degrees warmer I only need 115W. Wait a minute that doesnt sound right, I think I f"ed up?

Can I ask a question here. I have my heater in my sump in the unheated garage. I notice the heater in the garage turns on even though the tank is at 80 and the heater is set to 78. I assume the sump water is just cooler then the tank since the garage is unheated. that parts no big deal as the tank never goes above 80. My question is since I don't know how this heater will hold up in the winter I want to add a second set to like 76 as a back. I was thinking about putting the second one in the tank so it would have a better chance of keeping the tank from dropping since the tank is indoors in a heated room.

if there is alot of water flow it doesnt matter where you put it

both heaters would work as the temp will actually fulx a small amout in all the tank.

Yep. I may still use two even if I do put them in the sump side by side.

.in fact using 2 heaters may even keep enegry cost down

Curious.
