Yeah they have those but can't even do that right now. It looks like from the guess sticks...I have lowered my cya alot reading 30-50. If that is truly the case, I am gonna turn on the inline clorinator and let the tablets that are in there get used up, as never to have anyone turn it on again It should lower my ph with the use of triclor and it seems like a can afford the raise in cya a little. Am I thinking right here or not? I will be taken a sample to the pool store tomorrow
