We installed a new liner on 6/18. We filled the pool with well water and it was completely full on 6/21. I was adding some liquid chlorine as pool was filling because it was taking 3 days and we had hot sunny temps. (Note) When filling pool, there was rust colored sediment that came from the hoses. I added salt and started balancing water on 6/21. I vacuumed up the rust colored sediment. Started SWG on 6/22 Within a couple of days I had white sediment in bottom of pool and SWG plates were covered with white. My readings on 6/25 were:
FC 4
Ph 7.8
TA 250
CH 210
CYA 50
SALT 3000. (Last year I kept it at 3200)
I added 2 more lbs of stabilizer, vacuumed up sediment and turned off SWG, added 1 Gal chlorine and 1 Gal MA. Water was crystal clear and had CYA up to 60.
I thought the buildup on SWG could be from high TA and rising Ph, so I figured I shut it off until I lowered those numbers.
I’ve been maintaining FC (between 5 and did drop to 2 once, on 6/30) with liquid chlorine and using MA for several days now and aerating the pool to raise the Ph, so I could continue with MA to lower TA. Water has still been crystal clear and have had no white or rust sediment on bottom of pool. Unfortunately, with the jets turned up and the high sun and temps, I’ve had some evaporation and have had to add some well water to the pool which is fighting me trying to lower my TA.
On 6/30 we cleaned the SWG with MA/water solution as per manufacturers instructions. White sediment cleaned right off the plates. I had the TA down to 140 so I decided to try running SWG because I was tired of dumping liquid chlorine in my pool.
This morning, (less than 48 hours later) I have cloudy water, white sediment and some rust colored sediment in the bottom of the pool and white beginning to form on the plates of the SWG again.
This morning’s test readings: (7/2/22)
FC 4
CC 0
Ph 7.4
TA 140
CYA 50 (could see dot at 60, but lost it before it hit 50)
SALT 3000
I now turned off SWG, added 4 Gal chlorine to start slam at 20. It is currently raining, but I will vacuum up white and rust colored sediment later today after rain stops.
Any idea what is going and what else I need to do?
