Sean, Thanks for the response, I've been out of town so could not respond to you until now.

Regarding chemicals, each week I add ~1/4 gallon of acid to keep the PH ~7.4 ot 7.6. The weekend prior to the chemistry I reported in my 8/18 post I added some stabilizer and I added a quart of a chemical used to keep the calcium from plating out in the cell and on the pool finish, I'm embarased to say that I don't know what the chemical was other than there were 2 products to choose from, 1 whose levels could be detected in a pool water test and the other that could not, I bought the one that could not be detected. That weekend I also added some salt as well. Please note that my issues with maintaining chlorine level goes back well prior to that point.

After reading your 8/20 post this evening I went out and ran the system test and got some data.

Chlorine level at 6:30 this evening: 1 ppm according to my home test kit (after running system at 100% all week since my 8/18 post, please also note that typically when my home chlorine test kit shows 1-2 ppm chlorine then I have my water tested at the local pool supply store the same day they tell me there is 0 ppm chlorine so my home test kit's accuracy is in question. Judging by the fact that the pool has some algae "shadows" on the pool walls I would say I believe the chlorine is currently 1 ppm or less. After taking this reading I turned on the boost to let the system run overnight and immediately ran a test of the pool pilot and it showed 18 volts and 6.5 amps.

3 hours later I read your post and then ran another pool pilot test and saw 18 volts and 6.5 amps. I did a force reverse and tested, it showed 18 volts and 6.4 amps. I waited about 1 minute increments to run more tests and got the following results 17 volts and 6.3 amps, 17 volts and 6.2 amps, 17 volts and 6.2 amps. I waited ~15 minutes and tested again getting 18 volts and 6.5 amps.

Any help you can provide would be greatly appreciated. I'm very concerned because the system failures we've had over the past few years have led to some small flecks of black algae in different areas of the pool, I can't afford to run with low chlorine for any period of time going forward.
