Have had two of these fail By Jay on 5/14/2018Jay wouldn't recommend this product to a friendhad one stay on, on a 125, tank was up to 86 degrees. adujusted the thermostat down and the heater hasnt came on since and now the tank is 76 thankfully because it has lids.
had another on a maintenance account where the coral wasnt doing so hot for about a month or so and the tank was relatively new with great equipment and care all around. so then of course when i grab the heater it is so red hot that i cannot hold onto it even under water.
so thats two of them failing in just a few months. i usually never write reviews on stuff but these should never be purchased by anyone who has fish and coral that they care about.
Sad loss By Laisper on 5/1/2018Laisper wouldn't recommend this product to a friendMy 100 watt lasted 2 months, was laying in bed like any other night and smelled smoke. Threw on a light and saw smoke coming from my tank, the heater blew up! Shattered into 4 pieces, no idea why. I'm lucky my animals are ok.
Unacceptable By Juan on 8/19/2016Juan wouldn't recommend this product to a friendBought the 250w heater. Have it conected to a controller and lasted a little over a year... will try jager next time.
So far so good. By NewFisher77 on 4/18/2016NewFisher77 would recommend this product to a friendOnly started using it 2 weeks ago but if you want a review now all i can say is it works.
Broke into two By Peyton on 3/31/2016Peyton wouldn't recommend this product to a friendI bought this heater in December of 2015 and did not even open it until March 2016. I submerged it underwater and waited 15-20 minutes to turn it on like the directions said. I turned it on and it began to work. I left it for a few hours and when I came back I smelled something burning, then looked in my sump and saw that the heater had shattered into two pieces. Maybe it was damaged during shipping.
Not worth the money By jayden on 8/15/2015jayden wouldn't recommend this product to a friendThe heater is great for heating the tank up but it is very hard to tell what you have set the temp at. Also it seems the the heaters temp prob is off because I have to have the heater set in the 84 degree range just to have it heat the tank to 75 degree. If I had the chance to get a different heater instead I would have gone with the flat cobalt heater with the two led lights. This heater has way more control but it is a little pricey. All in all if you really care about your fish then save up the money to get the more expensive heater. (Was not payed to right this for the more expensive heater)
Good for the price By George on 1/28/2015George would recommend this product to a friendBeen using this Heater for a few months now in my water change tank its it been doing its job. so far so good.

What watt heater for 120 gal with 30 gal sump
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.
What watt heater can I get for a 75 gallon tank
How is the temp set... does it have "high" and "low" settings or exact temp (example 75 degress) settings?
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
