Thanks Dave,

I plan on shocking tomorrow. The kids are using spa tonight. It is still too cold in michigan for me to economically heat the pool just yet.

What is the recommended FC/CC levels or ratio that I should shock at in the future? I installed a SWG when I built the pool, but haven't added the salt or fired it up yet. I was waiting till I had everything in balance and the water temp up higher before switching over. I am still adding chlorine manually.

I've always been a do-it-yourselfer (including building the pool)... so for me the kit is great.... definately a worthwhile investment.
