hello there reefers i just picked a new venturi skimmer brand name is won 75 cleanup venturi driven proteint skimmer came with sen 300GA pump,here is my question how do you get it to work i cant get it to form any bubbles and yes i tried to adjust the water flow. seems air is getting into the tubing some how the little air tube they supply you with fills with water my better half went back to the store today and they took it into the back and said it worked there for them. only when they put there u tube on to the skimmers we have purchases alot of supplies and fish from them and never had a problem. Just wondering if any one has any suggestions or had the same problem. thanks
