Hey guys. I just turned my pond on for the first time today! I have a helix skimmer with plumbing coming out of the back into hard pvc and sending water up to my bog. The problem is that I see a small drip coming from where the pvc fitting goes into the skimmer. I can't tighten it anymore since all the pvc is glued. I know it was super tight though. Is there a plumbers tape or silicone I could use to fix this? It drips about once every 30 seconds so not horrible but I want to take care of it. (The water in the bottom of the hole in my picture is from rain we’ve had). I’m glad that water was there otherwise I may not have noticed the drip.
