First, thank you for your reply.

> Your high CYA is from those tabs which are presumably trichlor. High CYA will not hurt you but it will cause you to have to run higher than normal chlorine levels or you will constantly be battling algae.

In reading some of the water chemistry stuff I have seen I thought I saw something that said I should turn to non-stabilized chlorine instead of stabilized chlorine. If I do that, and if I watch my chlorine levels carefully, will the CYA levels drop? Or must I drain and refill? I ask because I live in Arizona and water is a precious (and expensive) commodity. Our pool is very small, but if I am constantly draining and refilling my water bills will not reflect the small size of the pool.

I will look over the guide you mentioned before I do anything. And thanks again.
