Just started with our pool (bought 20yr old home last November with a pool of unknown age) and planning on using TFP to keep it clean rather than the pool store nonsense.
I got my new TF-100 test kit in yesterday and immediately followed the directions for doing a CYA test, as that's the number I'm most concerned about. As I feared, I'm looking at right around the 200ppm mark. (1/2 diluted, dot disappears around 100, maybe just a hair more).
I have a submersible pump and some hose on order, and a plan for draining. If my testing is right I'll need to drain somewhere around 80% to get to what I want. How will I know when I've drained enough? Also, it's a plaster pool, so are there any pitfalls I should be aware of. The water table is pretty far down here in the desert, so I'm not worried about the pool floating, but I am concerned with cracking or buckling of other kinds. Should I be? I don't know how old the pool is, but it's in very good shape.
Seems pretty inefficient to me to drain, fill, drain, fill, drain, fill to get to the number I want, so I'd rather just do it in one shot if I can.
Thanks!
