    Last night I changed it to 79. This morning when I woke up it was 73.

    Is the heater on 24 hours a day? If it is, then you know it’s just underpowered, but I wouldn’t think that’s the case. 75 Watts seems like a good size for 20 gallons. Fish and corals do tolerate colder water better than warmer but I can understand that you want it warmer than it is.

    Since there’s a discrepancy between the heater and the thermometer you may want to try a third thermometer so you can make sure it’s not an error with the other thermometer. The heater is likely the problem but it’s good to make sure.

    I was having better accuracy when it was in one of the side chambers of my all in one innovative marine 20. But I decided to fill that chamber with marine pure balls and put the heater in the center with the return pumps. Does the high flow vs the low flow effect the heating?

    No -- mine are in the center of both my Innovative Marines.

    Well I wanted to get a second heater and thermostat. So guess I'll get one soon and do some trials to see what could be the issue.

    Run your heaters through a ranco controller then just turn your heater on higher.

    Your Nems really prefer stable temperature. Best way to obtain that is two heaters and a controller so you keep the temp constant.

    so, apex jr seems like the lowest tier of the apex controllers, but would work for my tank.


    any other things for a controller that would be recommended to have?
    think this would also track my temperature throughout the day and correct my issue.

    Apex jr is perfect for those things and especially for controlling two heaters in the tank for you. I actually think it's one of the best bargains in reefing as it's expandable as your needs grow. The only caveat to it these days is it won't run the forthcoming Alk monitor.

    Bear in mind that the Jr can only have 7 modules. PH and Salinity are already 2. Once you get the hang of it, modules add up fast. FMK (flow), ATK (ato), VDM (0-10v), WXM (Ecotech), LDK (Leak), EB8, DOS (doser), WAV (wavemaker pump) etc

    I would suggest you start looking at the 2016 Apex instead, there are reasonably priced used ones out there. That way you future proof your purchase.

    The upcoming Trident (Alk/Ca/Mg monitor) is only compatible with the 2016 Apex.

    just learned that the heater can be calibrated. mine is probably not correct. next to start some trials to get it set correctly.
