Thanks Watermom,, Most of the HW was from years past on the forum. I did a Baq to chlorine swap on this pool back in 2003 by PoolDoc's method. I know we used to post some together back then and I was on the forum quite a bit but have not been on here so much lately. Guess I will need the Borax though,, over shot the PH with acid. It changes a lot faster on fresh water than it did with the old water. One reason I asked about the borax when I was on the forum back then someone on here was doing some work on larger amounts of borax to act as a buffer (wish I could remember who it was). Never heard the final results though. I still have one of PoolDoc's kits and probably enough drops for this year and part of next. I bought a refill kit from him right before he quit selling them. I have some bleach in it now and have fixed up a jug with a dripper to keep putting it in slow when I am gone for all day. This should get me by till I get the CYA up. I am looking to start it at about 40 to start with. Do you think that is high enough to start with. Thanks for the advice,,,,,
