Heater fro 185 gal

[chark]

Would it be alright to put the heater in the overflow in the aquarium? How big of a heater do I need for a 185 gal tank? I have one 250 w heater. Will that be enough? I keep the house at 76. The aquarium has had water in it for a day and is at 72. I just put the 250 w heater in. Oh yea, I do not have anything in the aquarium but salt water so it is not an emergency.

I youst to have 1 250 watt heater in my 120g 30g sump with it the overflow and it never turned off way to mutch water to heat up and i keep mine at 77 to 79 i added another run 2 250 watt heaters and works great but mine is 120g and 30g sump, so maybe 2 or if not 3 but thay make 500w and 1000w heaters most have a external controler but that all depends on lighting return pumps how many pumps you run and anything in tank that heats water, most say youse 250watts per 75 gallons

You can put it in the overflow (it's where I have mine on my 45g), but that gives the heater a very limited amount of water and limited amount of time to have an affect on the water temp, especially on such a larger water volumn as a 185g tank. As far as the capability of your 250watt heater, that depends on the manufacturer. They all have different tank size recommendations for their heaters. Once you get your lighting on and pumps running, the temp will come up in your tank on it's own so your heater(s) may not have to run that much. I would recommend you get another heater, probably the same wattage, and run both on your tank. That way neither has to run full power all the time and if one fails you will still have one to prevent the temp from falling much.

Why not just stick it in your sump?

I agree, you have a 40 gallon sump, should be plenty big.
