Until I can buy a new test kit I am using my kit that only tests up to 5 ppm of chlorine. I know I have read on here before about using that test somehow to test higher levels. Can someone fill me in? I have a CYA level of 110 so I think I need to test around 9-15--right?? I'd love to lower that CYA level by draining and adding water but water is so EXPENSIVE here. I'm hoping that switching to bleach only (I've been using bleach and an auto Trichlor feeder up til now) will eventually lower that CYA level.

Sorry to have to ask for old info--I sure miss all those old threads!
