We moved in our house with this pool about 3 months ago. The wife mentioned yesterday, "the water looks the best it has since we moved in".
Thanks for all the advice.
On a side note, when I was getting a sample tested at my local pool store for metals the other day, they were kind of busy and 3 people were in front of me. Every one of them had CYA levels that were off the charts and the guys that worked there were acting like it was some big mystery as to how this was happening to all of their customers right now (all the while they're selling trichlor tabs by the truckload).
Seems like a great business venture opportunity for someone to come up with a puck that doesn't add CYA and other "inert" ingredients.
