Ok I have a salt pool and am tired of the thing going out and constantly costing me a fortune for parts. So I decided to switch to Chlorine. I made the switch at the beginning of summer after I had already brought the conditioning up to 60 CYA. Everything went fine until we went on vacation for a couple of weeks and the chlorninator ran out of pucks (wife forgot to refill before she left). Since then I have been battling the ****ed thing and have several spots of black algae and am getting the green fuzz after 1 week. Throughout the summer I was using the powdered chlorox shock during the week to get things under control, but now it can go for a few days and it is starting to turn green again. I found this site so I ordered the Taylor 2006 kit so I could start the slam process. I just walked back inside after doing the CYA test and noticed that my sample wasn't even to 100 when I couldn't see the black dot, so I drained the applicator to 7ml and filled it to 14ml with tap water and sure enough it goes to about 70. So I am guessing that that puts me right at 140 CYA. So my question is would it be better for me to go ahead and drain off part of the pool to reduce the CYA before starting the SLAM process, is this something that is going to be causing me to fight it year round? FYI since finding this site I have been using liquid chlorine as my source of shock. I live in Houston so the temp is starting to fade down here and my pool is a 25K gallon sunstone peal (aggregate with Portland cement).
Thanks for any input
