Thanks Rangeball, I was afraid of that..... I started a thread asking about how to tell when I need to shock using an OTO test and only got one reply - telling me I needed a different tester. How do all the people using these tests know when to shock?!?

Snowymoon - I tried your rigged water-sprayer to try to get the temp down in my pool I had thought of something similar but was waiting till I could order another adapter and length of hose so I could use my skimmer at the same time. Saw your pic and thought "why wait?" I LOVE the sound more than anything, I think!

Thanks, Amy
