I have an Intex 16' x 48" Ultra Frame pool. This morning I unplugged the copper plates so that no more copper ions will be generated during chlorine production since our copper levels keep creeping up (currently at 0.3 ppm). I ran the SWG for about six hours today since the FC was a little low this morning (~ 1.5). My kids played in the pool all day, and I wanted to run the SWG for a couple of hours tonight to make up for any chlorine that might have been used up today. Shortly after turning on the SWG, I could hear beeping, and I am getting a code 92 (high salt) alarm. I turned the system off, and measured the FC at ~ 3 ppm. Just yesterday I took a pool water sample to our local pool supply store, and they got a salt reading of 3000 ppm which my manual says is ideal for our pool. I used my AquaChek test strips and just got a reading of 3245 ppm. I have not added any salt to the pool since we put it up about 3 weeks ago. About 2 weeks ago the pool store tested our water at 3300 ppm, and the SWG was working perfectly. Do you think that unplugging the copper plates could be affecting our unit? If we need to partially drain the pool, how much should we drain to start out with (couple of inches, a foot)? Any advice would be appreciated.
