Not the pump got a new one still not working. Just got off the phone with Tunze and will be shipping it to them to be fixed. Still would like to know if the float switch for my apex would be better.
If you have a pump laying around, and you have something to hang the float switch, sure you can make an ATO system out of that. Just need to make sure you don't turn the pump on and off as the float switches change states. Have a delay a few seconds or minutes between on and off of the pump...
