Gurgling POC overflow

[Doug]

So fine. Nobody cares how I fixed it. Gonna tell you anyways.

Simply removed the air tube controller thingy majigy that everone says to put in the top air hole to adjust it. Yea, that worked well.

Once removed, the open 1/8th air hole works just fine for my pump. Nice and quiet or quiet enough.

Perhaps one needs a larger hole and larger sized air controller to allow for more air if needed ??

well in a skimmer salt behaves different than fresh so maybe so with a Durso.

Either when tuned my Durso, started with the water surging and gradually enlarged holes until the surging stopped, but still a little noisy. Kept going bigger then all of a sudden, quiet.

With each 2" Durso can fairly quietly flow between 500 and 1000gph and the hole size is only slightly bigger than 1/8".

Whoo, we knew, if left alone long enough, you would figure it out

But ya, SW and FW will flow different, just like in a skimmer

LOL Dan.

The surging noise is something else Mark. Now thats enough to make one go back to sumpless. Guess I figured the air hole w/controller was large enough but apparently only for fresh water.

once tuned there should be no more surging. now the gurgling into the sump no way around that with a Durso (or Stockman or Hofer as all draw air). Truly silent, need to go to the Herbie (no air, no noise)

[Doug]

Not bad in the sump. I have it below the water level, in a filter sock. Can hear it but fairly quiet, and when the skimmers running cant hear it at all. Now thats a problem in itself. Going to build an air silencer soon and if that does not work going to buy a new one thats silent.

Which skimmer is that, Doug?
