I really like the adjustable air pump because I can dial the air back so it gets sucked in . I can if I want close the hole of and turn my airpump up and it will supply my skimmer with enough air for it to have 100% saturated o3 but I don't . I only close the top hole and turn up the air pump to see if I have any blockage inside my ozone unit . If so I clean it .
Do you mean the T valve that you want to close the top hole to check your Ozone.
Once again, thank for the helpful information.
