I'm here Bonibelle. Thanks for asking.
We just got back from Florida yesterday. The dial up connection down there is only slightly faster than snail mail so I don't do much on the Internet.
All the skin problems have cleared up even though I spent a lot of time in the pool and surf.
The tub is in pretty good shape even though it sat for 10 days unattended. Once I get it back in balance (very low mps) I will get in and see what happens.
If the problem returns I will have no choice but to change to a bromine or chlorine tub.
