I had a small leak develop in this elbow from the return pump into the tank. It’s very gradual but I saw the dried salt around it. I used DAP 100% reef safe silicone around the joint to seal it. The caulking is on the outside of the pipe and will not be in the water. The directions say 48 hours to totally cure but I had to turn off my return pump to make the repair and can’t leave it off that long. How quickly could I reasonably turn the pump on? Like I said, it’s a small leak (maybe a drop every few minutes) #reefsquad can you help? I’m on a time crunch!!!
