Tunze Water Level Controller Pump

[martinmcnally]

I find that the pump that comes with the Tunze Water Level Controller is pretty useless and only lasts me about 4 months or so before needing replaced. Anyone know of a better pump that can be attached to that unit? I think it only takes 12 volts or something like that.

I was wondering about attaching a 12v relay switch to the controller and having that switch on any regular 120v pump.

I think the problem occurs if the bucket ever runs dry with the pump on, it doesn't have any built in auto shut off.
