For about a year now (seemed to start last August) either something crazy is going on or my SWG is not working. I have had my cell replaced, sensors replacement, and board part of the unit replaced. I am ready to switch over to straight chlorine. I have been dumping chlorine in by hand every night trying to maintain the chlorine level. Generally when I dump in the recommended amount of shock by the next morning it is all gone. If I dump in double the amount it stays in about a day. Before I started getting everything replaced on the generator I had the water tested several times and the water was perfect. And for the most part the water is always very clear, that is, as long as I don't forget to dump in more shock for more than a day or two. I have spent so much time and money on this, that I am ready to have someone come fill it in so I can get my yard back.
My water levels are a little off now, but were perfect. The last thing replaced was the board for the SWG. After replacing the sensors it said my salt water level was high. Which I told the rep was impossible seeing how last year the levels were perfect and I have not added salt in two years. So he convinced me to drain the pool down 4 inches and add water anyway. After draining water, it would flick back and forth from high to good. So he then replaced the board. But now it says with new board that the salt level is fine (3300) my ph is little low 7.2 TA little high 130 and CYA was a little low about 50 (I have since added 4 lbs of HTH CYA). My phosphate level is a little high about 200.
Sorry for rambling but after replacing everything, (the field guy even put the cell in a bucket and said it foamed meaning it was working), I still can not get the FC level maintained. It will literally goto to zero if I don't add myself. I have the SWG sensors turned off and the percentage set to 100%. Also I have an automatic cover, which rarely comes off during the day. So I literally should be using very little chlorine. In fact last year I had a problem with the chlorine level always running high.
