Thanks for the advice! I am definitely concerned about that. So far it looks like it drained about a foot over 12 hours last night (7PM to 7AM) from siphoning, so I am planning on letting it siphon another foot during the day so that it has about a foot in the shallow end and start filling it up from there.
Hopefully doing this procedure over and over again until the CYA is at a normal level and ready to swim in the middle to later part of May.
Has anyone used the process of siphoning out of the bottom of the pool while currently running a hose to replace water at the top, or is this a waste of money? I don't see it being any more or less of a waste than what I am currently doing with dropping 2 feet at a time and then refilling/mixing and then dropping another 2 feet.
It appears that having a high CYA level in a pool is often caused by the trichlor chlorine feeder. Now I understand why bleach is stressed so much over the trichlor pucks because the pucks add stabalizer and the chlorine gets used up, but the CYA builds up.
I think I will still use the trichlor pucks as I have a $100 bucket full of them, but just at a very low level and keep a steady eye on CYA and make sure it doesn't creep up.
