    DOS over pumping

    I'm only pumping tank water right now, so I'm not crashing my aquarium, but can anyone tell me why it is randomly pumping these large amounts?

    Do you have anything in the advanced tab?

    Did you set either of them to ON instead of AUTO?

    I had them both set to auto the whole time, I used a scheme from the discover search. The schemes were by user Saltbank. When I look over them it looks like it should be good, can it create a siphon and just keep going sometimes?

    No; the DŌS log would not show dosing activity if a siphon was created due to some sort of failure.

    Is there anything touching the priming button for the Ca side of the DŌS, such as tubing?
    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    Did you check the advanced tab (gear icon)?

    The code on the advanced tab looks the same as the code on the advanced tab for the ALK, just different times.

    I don't believe anything was touching the priming button... but I'm going to add more water and keep a closer eye on it. I sat it and then woke up the next morning with the CAL side ran empty, I haven't added anything since.

    Alright, I 100% got a bad DOS... now the right side, CAL in my case, runs non-stop unless I unplug it from the power completely... Guess I'll figure out how good the Apex warranty is.

    Is yout clock set on your dashboard? is there one or two times? I had this happening before and I had to reset my clock. After that it started working right for me and has until the clock had to be reset again.

    I had to send it in and get it repaired, a board inside had to be replaced. It is functioning perfectly now.
