Okay, Okay I went and did it...I violated Andy's First rule of Skimmers, Once it is adjusted, don't screw with it.
I have an ETSS
Reef Devil Downdraft Skimmer with a Mag 7 pump. It was providing a lot of skimmate, but leaking kinda bad. So I taped up one of the unions, and had to readjust it.
For the water level to go up in it, I have to open the exhaust valve from the outlet, and vice versa.
The problem is now , to get the water level up high enough to push bubbles up the column, I get a water spray from the air intake. I added about 3 foot length of tygon tubing to avoid getting my floor wet, but I see about an inch of water coming in the tygon tubing. I reduced output flow and the water level goes down, but I can't see any skimmate nor even any bubbles in the riser column. Think the skimmer is now broke?
