Hello Everyone. So a little back story, pool was completed in November and after the 2 week startup was done I had the start up company do weekly chemical service since I was traveling in Dec. I cancelled yesterday and assumed service today. Below are my TF-100 test results vs the pool store test results (looks like they used a giant Taylor kit marked service).
TF-100 / Pool Store
FC =5.5 / 3
PH = 8.2 / 7.8
TA = 140 / 120
CH = 375 / 290
CYA = 45 / 45
CC = 0 / 0
My main question is why is FC so different? Is it because I used a FAS/DPD and they just used the drops (I think its called OTO?) Also the service company came on Mondays, looks like I used almost no chlorine......Were they just making it super high to last a week?
What about the difference in Hardness?
Anyway I adjusted the PH this morning. looks like 16 oz of acid did the trick
