ReefKeeper

I don't have a ReefKeeper, but the only way to do this would likely be if your Reefkeeper can control your ATO (likely not built in functionality). What I would do is turn on the ATO outlet for a few minutes then off again after the time has elapsed. That way you know for sure that the ATO is only running for a certain amount of time. That is what usually is done with the Apex and an ATO.

This function would be easy to program a timed ATO with the reefkeeper lite

I have the reefkeeper elite and use a float switch to control my ATO. you can buy these right off the digital aquatics website I forget what module the float switch gets plugged into though. I also forget exactly how I set it up but I think you have to do it with the alarm function.


here is a good link to a video that explains the process better than I could.

You can also program a maximum run time, but the problem with doing it that way is that even if you had it send you a warning, you would still need have Internet access to reset the ato after a long run. A float switch is a better solution
 
Plug the ATO into the PC4 (any port).
Using the SL1, SL2, or SLX you can run a float switch on the "switch ports" When the float switch triggers you have have that action programed to turn off the ATO power outlet that it is plugged into.

Download the manual to learn how to specifically trigger that action.
