I've been a bad pool owner and ignored my AGP all winter long. Well the days are warming up and I've decided that its time to get things going again. During the winter, I kept my pump running, but the SWG was complaining about low salt, so I turned it off. A test at the pool store in November showed I was at 3200ppm salt. I figured it was too cold or for the SWG to run and due to a baby on the way, I didn't follow up. This weekend I took the SWG apart and used vinegar to ensure there was no calcium buildup on the electrode plates, then took two water samples down to Leslie's to have them tested. The results are as follows:
FAC 0
TAC 0
Salt (first test was 1600, second was 2300) - two different meters at the local pool store
CH 250
CYA 60
TA 120
PH 7.4
Copper 0
Iron 0
Phosphates 200
I'll add some more Pool Perfect Plus PHOSfree to get rid of the phosphates, and the FAC issue is pretty obvious; the SWG isn't producing chlorine. I added the last 8.8lbs of salt that I had and several hours later got it re-tested (yeah, I know I should wait longer). I then added another 40 lbs of salt to the pool. If I just needed to bring it up from 2300 to 3000 in a 7000 gallon pool 40 lbs 12 oz should have done the trick. I can get the SWG to start producing bubbles and it does so for a while (not sure how long that is). I'll come back outside some time later and I get a code 91 (low salt) flashing on its desiplay. I figure I should be around 2900 ppm. We got very little rain this year and I back-washed the pool yesterday for the first time in probably 6 months so I can't figure out why I'd go from 3200, to 1600 to 2300ppm. I don't trust either of the electronic gauges at Leslie's so I'm left with two alternatives. Either I could so buy some salt test strips (the Aquacheck version) or make a 3000 ppm solution and take it down to Leslie's then test it with both of their meters and compare it against a new sample from my pool.
Another thing that's got me questioning everything is what looks like either rust or rusty colored alge (it seems to move within the water flow) IN the SWG where the extension from the plug meet the electrode plates. WTF?

Any suggestions on where to go with this? I think that piece is sonically welded to the plastic that holds the electrodes so I'm not sure I can take it apart otherwise I would have done so already. It looks like it needs a really good scrubbing if you ask me.
Thanks in advance guys!
