Hi Deb!
Thanks for replying. I did add the chlorine shock last night after the kids got out of the pool (it was dark outside ) and this morning I only had a tiny bit of dark dead looking algae at the bottom of the deep end. I guess all that brushing and the chlorine shock did help!!! YAHOO!

I will get a drop kit today and I'll post the numbers on a new thread. Thanks so much for answering my post, I really appreciate it. I'm glad you're swimming in your pool finally. We are having a heat wave here in Michigan this week so I know we'll be swimming--Guess we'll just have some red eyes Oh well, it will be worth it.

FYI-I have an inground vinyl lined pool with a sand filter that is 20,000 gallons.

Have a great day!

Sue

p.s. what does cya stand for???
