Yeah..it leaked..they patched it and it still leaks. I think it's a pressure thing. When the tank is full the water is 6" above where the leak appears..and it takes nearly an hour for it to appear and it's so very small that it almost evaporates as soon as it appears with the room temp. It has to be the tiniest of pin holes that with the pressure and volume of water a drip is squeezing through. I need to get it sorted though and I don't want to rely on salt creep sealing it.
