would like to see picture of your skimmer with it on.So I upgraded the venturi yesterday.... and ... o boy ... what an difference... is one of those things that should be included with this skimmer ... what an difference... Jebao DCP is now running at 90% and not an 100%... no need to split ait intake to keep venturi clean bc inlet is much larger and foam..... well foam is so thick I thought it was a sponge....I also removed the gate valve all together bc at this point I control it with the speed of the pump ... gate valve .. even tho fully open was still presenting an restriction to where I could only run the pump at 70% bc anything higher than that skimmer was overflowing with valve fully open..upgrade your venturi ... you get completely different results ... for better I belive... below is pic of what I got of Amazon ... just have to remove the smal spring and ball and game on after that
