Thanks for all the help!

I don't know the volume of my pool, I only know the measurements (see: My Pool above). It's an in-ground concrete pool of some kind, and not vinyl. Is there any particular disadvantage (other than not being able to use my OTO kit) to running high chlorine levels? Will the CYA come down over time to where I can use the readily available OTO kit?

I'll ditch the pucks. Are the 10% liquid chlorine bottles from Home Depot okay? Any thoughts on how much to add to add?

I may have done the drop test then. I mixed up a solution, counted the drops 'till I coulnd't see the black dot, and did the math to get the 110 CYA number posted above. I'm not sure what kit I have. I ordered using the one in your signature (specifically so that this site would get $$$), and my receipt from Amazon says I ordered the K-2006C kit. However, I received the kit from "In The Swim", the box says it's a K-2005C, and the shipping label says it's a AB230???

I've not added algaecide, but I DID add Leslie brand "Ultra Bright" clairifier per Leslie's instructions several weeks ago. My father-in-law (previous owner) claimed this claifier "works wonders" on green pools ... any thoughts?
