heater for 144 gallon tank

[agrainger]

about to start my new tank.

using the method of 4 to 5 watts per gallon figured 600w would be good especially considering i am planning on a discus tank that has higher temps.

i ordered two jager 300w heaters. when i got them in they say they are rated for 159 to 264 gallons each.

my question is should i use both or just put one in and keep the other as backup

use both, one is an active backup

You can use both if you want, but you only need one. I use 1-250 watt Jager in a 150 gal. discus tank kept at 86 F, and it's fine, and 2-250 watt Jager heaters in a 240 gal. with a 55 gal. sump. Using 2- 300 watters on a tank under 150 gals. is unnecessary.

Darell, do you think one 300 would be ok with a lower room temperature of, say, 68 degrees. I would add that tank insulation might come into play.

On a 150 gal. tank for example, I would say yes, if the heater was a Jager. From experience, I don't trust other brands. My tanks are non insulated, and the room temp. is around 70 F year round.

I'm with you on the jager.:D

Keep both and use one as a backup. Having 2 doesn't hurt but not really necessary for a 48" wide tank in living space. Keep in mind that these Jager heater are big so putting 2 in a show tank doesn't look good (IMHO). If I was doing a show tank like yours, I would use the Jager with an inline heater module or get a Hydor inline. I know most people trust the Jager over other brand but I use a single inline Hydor in my 90gal. My tank has a controller so I get alert instantly when it fails.
