I'm a new pool owner. I've been lurking the forum for the last 6 months since we built our first pool back in November. We've been doing all the maintenance so far. Every week we take a sample to a store and they recommend what chemicals to add. Anyway we have these flakes that come out of the jets for the past month and they seem to have gotten worse. I've read a bit about what they can be (calcium scale flakes?) and I've tried to clean out the salt system with a 1:4 acid/water but to no avail. I have the latest print out from the store and I think these are the right acronyms...

We've been regularly adding acid (edit: sulfuric, not muriatic) like every week but we can't seem to get the pH down to 7.4. Our salt system tells us the salt level is at 3200 so I'm not sure if that number above is entirely accurate.

I'm pretty resourceful and try to figure things out on my own, but I can't seem to shake the flakes... Any advice you guys could provide me would be awesome!
