I've been reading this forum for a few weeks now and found it very useful (easily worth the $30 donation I just submitted).
I bought a house a couple months ago with a nice 25 year old 13,000 Gal, semi-rectangular, plaster finished gunite pool + spa. It looks like it's been re-coated in the last ten years. The pumps seem to be in decent shape, but the heater long ago rusted out.
I actually lived in a house with a nice in-ground tile/cement pool in Libya for a couple years, but just threw in the pucks a couple times a week since I rarely used it (when I was there I was working hard, when I wasn't working I wasn't at my house). I already ordered up a TF-100 kit a month ago - sort of reminiscent of titration labs in Chem 101. It's nice to have all sorts of resources here to learn about things like CYA buildup, etc.
Just wanted to say thanks.
