I have done that, closed the air tap then slowly opened it to get the smallest bubbles.
I would say that the larger bubbles are caused by the water inside the beckett venturi. Looks like I have micro bubbles going into it.
Yep, did this last night
That would be ok if the drain was used; I only use the cup to collect so the air cant vent thus reducing the foam.
I will post more pics once the skimmers work in.
I do have a few suggestions which could improve the becket.
Have you thought of designing a recirculating beckett similar to the Deltec? Never seem any reciculating becketts
We don’t Sell BK in New Zealand as there is no market for too many skimmers.
I compared similar size BK skimmers with the Deltecs and they are similar in pricing.
