Tunze 3155 issues

[Nwest]

I have set up my 3155 up to my avast kalk reactor and for some reason my ato keeps coming on every 3-5 mins.

Nothing else is changing at all just keeps coming back on. The other night it dumped 5 gallons of top off through my kalk reactor.

No idea what is going on, anyone ever heard of this.

Never mind figured it out....

The return pump line had air in it and was restricting the flow.

Make sure you don't have a siphon, if the hose ends below the water level in the reservoir it will siphon. I don't think air in the line would be a cause.
