I don't know much about SWG and a friend has a pool at the beach that needs help. I expect the pool maintenance company to go nuts when I start messing with the pool, so I need to be knowledgeable about the details.
Will I find any data in the equipment manuals to support my claim that CYA needs to be at ~70ppm? I think it was Jandy AquaPure unit for SWG.
Will we be able to get an owners manual online? We may or may not be able to find the manual for the unit. We will need to fine tune SWG setting when the other stuff is correct.
Does AquaPure have a salt level reading? The water tasted a bit too salty to me, not sure if we need to buy a test kit for salt.
The problem, for those who are still reading, is that the pool has black spots in corners and areas with poor circulation. I brought my TF-100 kit when I visited the beach and found pH at 8.2 (!), CYA at 0 (!), and FC at 0 (!). TA was high at 170. We adjusted pH to 7.2, added CYA to 30 ppm and shocked overnight to FC 10, TA reduced to 130. That was as much as we could do, we had to leave as company was coming for the week with lots of kids. No idea of what SWG was set at, I assume it was running near full blast.
Six kids were in the pool for the next 6 days and on the 3rd day the pool company came. They said FC was "great" and pH was "sky high". The kids in the pool had stinging faces and lips. I suspect the kids had the pool slide running all the time, adding high TA water to the pool. Of course, pool company thinks I am a nut that made this happen by messing with their pool.
The plan is to adjust pH then to shock properly to kill green algae in small pits in the plaster. Then we will adjust TA which is high and fine tune the SWG which will be too high when we get CYA up to proper levels.
I don't know if salt level is OK, or how to adjust SWG; how long that may take to get it balanced.
I don't know how to compensate for a pool that has no activity for a few weeks then 6 or 10 kids in it with no one around that knows how to monitor the chemicals to adjust for that. I can teach the owner, but they are only there every 2 weeks or less, typically not when the mass of kids and relatives visit.
Can someone walk me through some of these issues??
Question; the pool was rather salty tasting. Would salt levels go up after increasing CYA level? If we adjust CYA to
