Ca reactor trouble - suggestions ?

[andestang]

I'll have to emty the unit and check the media. I'm not sure how old the media is as I bought it with it in the unit - maybe a year and a bit ? The pump draws from the top of the main chamber so as soon as that air pocket gets there the pump quits drawing.

I find if I let my media go too long I get this phenomenon. It's really hard on your pump too BTW.

Also I'm curious how you have your reactor fed? Typically the effluent rate should not be affected by a bubble in the recirc chamber. That's another reason I'm thinking it may be media clogging...
