Heating question

[scubadude]

I upgraded my sump form a 40 gallon diy to a trigger 34 sump. I went to put my heaters into sump and there too long. I have a 120 gallon tank and was wondering two things:
How many heaters does everyone run and what total wattage for that size setup.
Are there any high watt heaters that will fit into a 14 inch sump

I would use two heaters with their own controller or with protection from an Apex type controller. I would consider something like this. https://www.bulkreefsupply.com/eheim-jager-trutemp-aquarium-heater.html

They might fit in a 14" sump.

I use the double version of this to hold my heaters in the sump. https://octoaquatics.com/octo-strong-heater-holder/

Depended on your climate, 500 to 600 watts should be able to heat that size tank. The cobalt neotherm would be a good option. Two 300 watt heaters and they're only 11 inches long :)

Most 300 watt are 19inch the colbolt look like,they will fit. Price is steep tho

Agree, price on them is pretty high. But I will say that after the redesign, they have given me no issues whatsoever and keep my tank at the most stable temp out of any heater i've used :)

2x250w jagers for ~150 gallon system, northern United States.

I like the finnex titanium ones. On a controller of course. They are shorter than the glass heaters and not as expensive as neotherms. I usually follow the rules of thumb of 3-5 watts per.gallon depending on where you are, broken up into two smaller heaters.

I run 3x300 watts on a 125 gal in northern Pa if there’s me fails the other two will keep it up to temp
