Heater for 230 gal

[Rmckoy]

We currently have 1 heater on the back of our display .
sadly I might have found why the water felt too cool .
It was unplugged ( I think my wife plugs the vacuum in while I’m at work lol

Upgrading to a new heater what would work best but not in the dt

Use the old 5 watts per gallon rule and size for 1.5x your need and get two.
