What I don't understand is how the foam moves out the Y? Jim,

The PS was located in the third chamber of a gravity flow filter. A pump was drawing out of this chamber and Teed off to feed both the PS and the return to the pond. The foam is carried up through the Y by the air flow pulled down through the PS by the falling water. An air pump located under the PS would probably enhance this effect.

Basically, Yes.

Everyone Knows that TTs or Shower filters tend to produce a stable foam. This is one method to collect and remove it. It may not be the best way for all situations , but it could work well in some.

Thanks Dan,
Is the bottom of the PS suspended in water just below the Y or does it rest on the bottom of the sump??

Suspended.
The sump that I had it in was a poor choice because the water level fluctuated quite a bit. Just something to keep in mind if you try it.

Hi Dan,

I'm really intersted in PS design.Since i've built one,it didnt produce foam.I'm quite upset of it.After looking at ur design,i'm tempted to retry.Before doing so,i'd like to have some info from u.I hope u don't mind.

1)Does your PS necessarily need an air pump?or just water pump?
2)Can I just use 3" PVC pipe instead of 6" pipe(like yours)?
3)what is the egg crate for?to support bioballs(trickle tower)?
why did u install eggcrate just below the 3" foam oulet?(I noticed u installed 2 cuts of egg crate?
4)If I'm using 400 gph pump,is this flow rate sufficient to produce foam?Does this pump run 24 hours a day?because i have already had that pump,so that i can save up money
sorry 4 the many questions.bcoz i'm quite excited.in addition,my pond has been suffering from foam for 4 months .thanks a lot
