Thanks for the encouraging words, stma! We are delighted too, it's been a treat to not wake up to the dread of "what weird color is the pool today?" So far, we're clear, blue, and holding!

We still haven't changed the sand though, and I'm thinking that we probably won't until next summer, since everything is working fine and the season is almost over.

I know what you're saying about the pool company, but at the same time, I can't figure out why they'd recommend us to NOT spend more money! They've been pretty good actually. They have also convinced most of their customers to convert from Baquacil, and I'm sure that's true because they barely stock much any longer, as opposed to two years ago when half of their floor space was devoted to it.
