What watt heater can I get for a 75 gallon tank
Question by: Mitchell Wong on Nov 13, 2017, 12:59 PM

We would suggest going with a 250-watt model or two 150 watt units. Usually, two heaters is better than one because if one fails then you will have a backup that will help keep things from swinging too quickly.

How is the temp set... does it have "high" and "low" settings or exact temp (example 75 degress) settings?

Hi there,
The Accu-Therm Heaters have a single dial setting on the top of the heater that you can turn to your desired temp. The heater will be able to keep a steady temperature that is accurate to ±2ºF

what watt heater for 120 gal with 30 gal sump
Question by: Daniel on Nov 23, 2013, 10:32 AM

Hi Daniel,
The 200w heater will heat up to about 55g of water. Your tank is about 3x that so you would need 3 of the 200w heaters.
