I found my leak! On the floor in the shallow end, near the steps. I made a version of Al's dye dispenser, and the beet juice worked pretty good. Only problem with the beet juice is that my family did not like the smell of them cooking, and would not eat them. I wonder how the juice from red cabbage would work? Maybe I'll try that next time.

Spent six hours Saturday slowly checking every seam. After two more hoirs today, I was working with trying to improve on Al's dispenser when I noticed a black "speck" that did not move. Turned out to be my leak. Verified it with the
dispenser.

This brings up another question, but I'll make a new thread for it.
