Hope this is helpful. THANKS AGAIN Don

Thanks for all the useful information. My CYA does decrease along with salt which indicates water loss somewhere. As I said, the pool was tested by a professional & I watched him pressure test all inlets, outlets, etc. with compressed air or gas, I think nitrogen. He could not explain the salt loss & suggested I seek an answer from someone apparently like yourself. I have a float valve to keep the pool full but no hydrostatic relief valve to discharge any excess water received from rain & we have had several inches of rain during the last 3 months. I assume that if I had a relief valve somewhere I could see it. The only outlet pipe is thru the backwash at the pump. The pool has not overflowed & I assume this is because the pool has now been covered for about 6-7 weeks. The cover is not very porus. The salt loss has been a problem all summer. When I first had the SWG installed there wasn't a problem for about 6 months & that was about 18 month ago. I have corrected the salt concentration to 3200 & CYA to 40 & will try to get it to the 60-80 recommended by you. I will be taking a sample to the pool store today to check my readings. I have checked my TA & it is 90 & I guess add some borax to get it down since the PH Is already low (7.3) Thanks again Don

I did take a sample to a pool supply place and their reading was only slightly different from mine. I also purchased their test strips and the salt is disappearing regularly. Is there a preferred 'salt' to purchase? I simply don't understand where it all goes. Thanks.

I have a in-ground 18,000 gal plaster pool wit a Aqua-Rite chlorine generator which is one year old. The system works well, however, I must add 25 lbs of salt per week to keep ppm at proper level of 3000 ppm. I have had the pool checked for leaks by a professional & reports that there are "no leaks found". Does anyone have a clue as to where the salt is going? I back-wash only once every 3 or 4 months. The pool is covered. All the information says this is not normal. Any idea's out there? Thanks Don excessive salt usage
