First off, I found you guys before I hit the pool store, so I'm ahead of the game already.
Approx 20000 gal pool, rough estimate, 3ft to 8ft, 36x15
Vinyl inground pool
TFC100XL test kit.
My first tests, I'm a bit colorblind, but I confirmed the PH and CL tests with my daughter.
CYA 70 I went till I couldnt make out the black dot at all.
CH over 450 drops weren't coming out even
Where do I start? Get the PH down, CL and FC up, or what? Thanks in advance. Yes, will input pool specs this evening, but I need to go get a beer, 112 out and summer still 3 weeks away.
