Hello from southwest Florida. I would like to thank eveyone on the site. We just had our pool completed a couple weeks ago, and the information here helped me make several decisions about it's construction. I already have the TF Test Kit and am looking forward to the pool company turning the maintenance over to me (they take care of it for the 1st 30 days.) After reading a few posts here I feel confident that I will be able to handle anything that comes up!
