    No experience with Fluval heaters, but a good formula for determining watts is:

    [(desired temp - room temp)/10] * gallons * 3 to 5 watts (varies heater to heater) = total watts required

    Ex: [(82F desired temp - 74F room temp)/10] = 0.8; 0.8 * 120 gallons * 3 to 5 watts = 288 to 480 total watts required

    All heaters are "cheap," so it's wise to invest in a quality controller, use multiple smaller heaters or both to prevent/mitigate failures.

    Here's what I'm thinking about... I've heard good things about these controllers.

    I've used the Fluval Es for several years now and they're my favorite. The first thing I do when receiving one is remove the plastic guard. That solves all the flow problems. I think removing the guard also removes the suction cup mounts but I have a sump so I just drop them in.

    Likewise to the other people who have answered your questions,

    I have at the moment 2 150 watt heaters in a new similar sized aquarium (was 3 but one blew yesterday) Im getting one more to allow for that built in redundancy, None will be under pressure or working hard to keep the temperatures.
    None of this is as easy without a sump though!

    Best of luck with the project

    IMO, the safest and least expensive solution would be 3 X 100 W heaters. None of them getting stuck could overheat the tank. If one dies, the temperature will not drop too much.

    I use 2 x 150W Eheim controlled by an inkbird controller on 90 gallon + 30 gallon sump. They keep up even when house is set to 55 during vacation in winter.

    I use all kind of heaters here, and generally do as many here do and stack up smaller ones verses one big one.. I subscribe to Willie's Philosophy on the failures being minimized.. I do have one gripe that anyone buying heaters needs to consider... The CORD Length!! Why can't they give you a decent cord length. I get saving costs but jeeze would it hurt to give customers a good 6-8 Ft cord. Its not like you want to use extension cords. Some of us have tanks scattered everywhere.. First thing I check now when I am considering a heater is the Cord. Yes I want the inside of the heater built well but it doesn't do me any good if I can't place the heater on the bottom of the tank horizontally and have enough cord to reach the power source and actually use the heater!

    I use two of the Fluval E300 heaters in my 75 gallon tank. I was using just one and the tank would cool down to 78 or lower at night, and I like to keep the tank at 82-84. Adding the second heater and putting both by high flow areas (filter returns) the tank stays a constant temperature.

    I find they Fluval Es work a lot better if you remove the plastic guard. It's not always practical though.
