Howdy everyone
Starting the process of opening my pool back up as the weather heats up, and decided to convert to SWG. I purchased the Circupool RJ-60 after 6+ months of research, and installed it yesterday. I'll post a separate installation thread for anyone that's curious.
But in the meantime, I'm dealing with some confusing chemistry issues. Here's the timeline:
Saturday: Pool had a bunch of algae after frankly being neglected most of the winter, and only occasionally tossing a puck or 3 into the filter basket in the off season. Dumped 2 gallons of 12.5% (though likely degraded down to 8%-9% by now) bleach into the pool and gave it a good scrubbing.
Sunday: Installed plumbing portion of SGW, tested chemistry. Results:
FC 0; CC 0; pH 7.8; TA 80; CH 250; CYA 45; temp - mid 70's maybe? The FC = 0 made me think my Taylor DPD powder may have been bad, since I had just added lots of bleach. Around 4pm I added 400lb of Salt to the pool, stirred it around, and then let the kids swim to further dissolve it. Pool looked a little cloudy maybe. I believe my pool is around 27,000 gallons, so the target salt is a little over 800lbs for 3600ppm.
Monday: Pool looks crystal clear, and as far as I can tell I can't see any salt in there (visually). Tested again, FC = 0 (or maybe a hint of pink). DPD powder must be bad. Turn on Circupool RJ60 - initially it says Salinity is 3600ppm, then drops a bit to 3400ppm, and then eventually 0ppm.
Drive to Leslies (I know, I know) to pick up a fresh bottle of DPD powder, which of course they're out of. While I'm there I figured I'd let them test it to see how my salt was doing (I know, I know, I hate them and don't trust their tests, but...). This is what they reported back:
FC 0.07; CC 0.14; pH 7.7; TA 88; CH 251; CYA 47; Iron 0; Copper 0.1; Phosphates 2479; Salt 3900.
How is this possible? How could my salt be 3900 after only 400lbs added. And are my phosphates eating my bleach? I know it's only been 24 hours since adding the salt, but it's all just super confusing. I have the Taylor salt test kit arriving Wednesday, and I've turned off the SWG generator for now until I can figure out what's going on. Any ideas?
