It works

I had a leak in my 360 gal Spa. It was leaking about 1/4 cup a day and I think it was coming from the pipe that runs from my filter to the pump. In any case, I removed the filter and poured 3 oz of the leak sealer in the filter bay and ran the pump for 6 hours with the water temperature at ~100F. I did this three times to make triple sure that I sealed the leak. It looks like the leak is now at least 90% sealled. I do still see a small amount of wetness just barely seeping out from the base of the spa. I'm not sure if there still has a small leak, or whether it is still drying out. But I'm pretty happy with the results either way as the spa repair people said it would cost me about $1000+ for them to fix.

Didn't work.

My 225 gallon spa was losing maybe 1/8 inch of water every two weeks and after trying spa leak sealer a couple of times, I saw no decrease of water lose.☹️
