Hello,
It's been a year and a half since last refill and setup. I haven't done a complete water test since last year. Getting ready for the new swim season and my recent TF-100 test results are off. I live in the Las Vegas desert. Water is clear but my plaster isn't the best. I have some plaster cracks that require underwater sanding and epoxying which I haven't done yet. I was waiting for them to fully exhaust. I have used the tan eraser to remove some of the dark circle-like plaster staining. I also have some new light tannish plaster staining around floor cleaning popup jets and around the sides of pool. It's only slightly noticeable. I read I should only do half drains so I don't remove too much pressure from the plaster. I'm not sure where to begin correcting these test results:
FC 2.0 <-- I noticed I fall from 3.0 to 1.0 within a couple days instead of the usual few days to a week
pH 6.7 <-- I had just added some. My pH gradually rises from 6.7 to 7.8/8.0 in a week
TC 1500 <-- Not sure how that happened
TA 20
CYA 0 <-- Filled tube and could clearly see black dot
Freshwater pool is about 18,000 to 20,000 gallons. I only use liquid chlorine and acid. I used shock at last setup and got CYA up to 30.
Thanks in advance for any help.
