My lagoon 25 seems to be sucking air in around where the 90 degree fittings that run through the back wall into the DT are. Is there a way to get a better seal so that air cannot be sucked into the tank?

Indecision may or may not be my problem.
Can you post a pic of the area you're talking about? I think I know what you're talking about but I just want to be sure first

I don't think it is sucking air, the water falling from the baffles pulls air down into the water which then gets sucked in by the pumps and pushed into the tank. I keep my water level like 1/4" below the baffles but that's just where I can get my ATO sensor at. I think the recommended level is around 1/2" below the baffles.

What makes me think that air can be getting in is that I can see water dripping out from where the 90 degree fitting goes through the wall. It’s been running like this for weeks now so I have no idea where else air could be getting in.
