Advice on this Skimmer

  • We are currently upgrading MFK. thanks! -neo
Hi guys! I was wondering why a gang valve is needed to control the air going in. Doesn't a skimmer need the maximum amount of air that a venturi can generate? If yes, will it help if we connect an air pump to the venturi barbed fitting? Tnx! :nilly:
 
to my understanding without controling the amount of air being forced into the venturi then you can generate too much air and overflow the collection cup, causing you a mess!! like i said not sure if im right but my skimmer directions said in BIG words not to let to much air in.
