Happy Monday! It's been a while since I've had a piece of equipment go haywire, so why not today?! For some reason my ATO decided to go nuts. I caught it in the act tho, ATO pump going furious dumping all of the 4.5 gallons of fresh water in to the sump, and the skimmer overflowing all at the same time..
I drained out the excess best I could and will test salinity in a hour. Total system volume is about 65ish gallons, so I don't think it'll move the needle too far. I'd definitely call this an ATO fail since it's supposed to know how long it should run before cutting the pump off. I know my skimmer cup was at least half full before the event, so even if it went nuts, that's maybe at most 3-4 cups of water volume to replace . No reason for the ATO to dump 4.5 gallons in one shot. Guess its time to add the redundant redundancy checks ;Woot How many freakin sensors do we need? Skimmer level sensor, ATO reservoir sensor, 2 x temp sensors, return pump chamber sensor, sensor for the sensors sensor, whee!! This makes me want to go with float valves or something low tech. Bad idea?
