Amazingly, 10 days later of adding nothing and his FC is down to 22 and his liner DID NOT fade one bit. I'm assuming the buffering of the CYA protected him....I can think of no other reason he has any color at all in his liner.
Actually, such posts have quite a bit of value, at least to me. They provide me with external confirmation of some of the points I've made here. For example, I assume he'd been swimming in the pool with no observed ill effects? That's what I'd expect, but it's totally contrary to what's found in all the literature.
