Wow quick reply and thanks!

I'll certainly keep posting updates. I can only assume that the old owners shocked using cal-hypo exclusively as there is substantial calcium buildup on the liner. The poolsolutions site is how I found this forum, so it is already bookmarked and heavily trafficked! In regards to using a fountain to aerate, do you have any suggestions on a money savvy way to use this method or if it is even worth my time? (The pool is a bit cold as the heater is defunct and it's been a crappy summer temp-wise so getting in and splashing isn't as fun as I'd like it to be). Here's hoping for warmer weather.
