Best heater options for 180 reef?

[jerod89]

I can't seem to find to many options as far as heaters go for a 180 gallon tank. The highest rated ones I can find are the cobalt neotherms, but they only go up to 200 watts. Would 3 of these work for my tank or does anyone have any better options? I have had a heater explode on me in the past shattering my 29 gallon tank so quality is very important.

EHEIM Jager is your best bet. hands down one of the safest heaters!

and instead of 1 big heater, it's always safer to use 2 smaller heaters. In case 1 heater malfunctions and stays on, that 1 smaller heater will not cook your fish

two EHEIM 300 should be more than enough

I went with 2x 250 watt Eheim Jager heaters for my 180 w/ 40 sump

I looked into those, but at 17-19" long they weren't going to fit in my sump.

You can lay them down sideways.

My sump is only 15" wide and each compartment is about 12" long.

You could see if they fit in your overflow box?

Mathematically that would work if the compartment was full of water. +1, use the overflow if it is deep enough

My geometry is a bit fuzzy since jr. high is over 50 years ago but I bet that they would be completely submerged on the diagonal. From top to bottom length wise. Depends on the depth.
