Ca reactor trouble - suggestions ?

Dave I checked that earlier and its all clear. I have a flow meter on the unit and it drops off when the air builds up. I'll take a pic for everyone to show.

Check the efffluent tubing to the tank and see if it clogged (this happens on the intake as well). Try blowing out the tubing, and if the air does not pass through, what I do is use a long piece of aircraft wire of the correct diameter and snake the tubing (you could also replace the tubing). You should see the stuff that comes out!

It could also be pressure due to aragonite breakdown as noted below. Let us know what you find and if it is not fixed post a pic for us.

A flow meter for the water effluent right? Located after the second chamber and controlled by a needle valve? Ya we need a pic

Do you have a separate feed pump or are you relying on the siphon created by the recirc pump? I could never get a steady flowrate using just the recirc pump. I guess this makes sense because the resistance will probably change as the media gets used up.

Anyhow my guess is if the media is a year old then this is very likely the culprit. A year is not a bad run. Seems to me an air bubble on its own shouldn't cause the pump to vapor lock (if you think about it, the pump should just suck that air bubble, shred it into a million little bubbles that trickle up through the media). I think it's more that the water has nowhere to go.
