Hello question. I just bought a new been running for 5 days. I have question so it came with some valve on the air inlet hose that you can adjust the air intake when i give it less air the bubbles are more slow at bottom of the collection cup. When I don't use it, the bubbles are much faster and pop really rapidly. Do i need to use this restriction. The skimmer sitting in about 8.5-9inch water.
