Thanks everyone. I am going to have my CYA checked at the pool place today. It is reading about 30 for me, wondering if I should add more, actually, I did add just 1/2 a sock full two days ago, and I know it takes about a week to register, so afraid to add too much more. The one pool place last week told me it was low in the 20's ( but this was after I didn't need any other chemicals! ), so I was skeptical, when my readings were higher. Man, you are all right, what other business are you at their mercy like this, they can tell you anything, and you do it ( well DID it!!) I am going to shock it and try to bring the PH down, and have chlorine added when I am going, with the pump running 24/7 and the Kreepy in while I am gone. That should hold it good? I am unsure of the borax, etc. so will just go this route. Want to learn more about all of this though!
