Vertex alpha 200

[SUPAkg]

I have been running a alpha 200 for a little over 6 months now and this skimmer is a monster. I recently did a deep cleaning on it. Completely disassembled it. Gave the pump a vinigar bath and scrubbed it down with a tooth brush.
For the past 2 weeks it has been over flowing non stop. I pulled it out again today and did the same maintenance on it besides the vinigar. Still doing the same thing. I read the trouble shooting advice and everything checks out.
The only other change to the system is that I had a bag of chemi pure in there that was taken out when I cleaned it the first time.
Any ideas? Anyone ever have this issue?

First make sure there is no salt buildup where the silicone airtube connects to the volute/nozzle on the pump. If there is salt creep or restrictions in there, the skimmer will overflow. If its clean and there isn't salt creep. Then your sump level is either too deep or you need to adjust the volutes nozzle. I would suggesting opening the nozzle a fraction of a turn at a time until you find a spot where the overflow is eliminated. Opening the nozzle allows more air into the skimmer and reduces the water flow into the skimmer at the same time. It's the water flow that will result in an overflow. Not the air. This is why salt creep in the venturi port results in overflows.

I'd suggest a starting sump depth of 8.5" and start with the nozzle 1.5 turns out. The sweet spot will usually be someplace between 1.5 and 3 turns out. Marking the nozzle with a sharpie pen helps to give you a point of reference as you are making adjustments.
