Scooter, I just found a leak in my spa by using something I read here (somewhere).....Get a bottle of liquid RIT dye and put it into some kind of sqeeze or spray bottle.
Squirt a little of it at the skimmer with the filter system ON, just to see what the dye looks like when "pulled" towards a "leak", then turn OFF the filter system and squirt the suspect areas.
It works great. I found a couple of good sized leaks and a couple of really tiny leaks around the spa rail jet tubes.
Hth,
