So, I'm new to pool ownership and made what I now know to be a huge mistake. I have been using Tri-chlor as my sole source of chlorine. Well, it was all going fine until this week when I came home from a business trip and found my pool in terrible condition. Green and Yellow algae.
I upgraded to a better kit (DPD only, no FAS ) and my results are below. First off, I have no idea why the kit says there is 5 ppm of FC. How could that be with the pool in such terrible shape??? Anyway, the CYA is waaaaay to high, so I intend to drain 70% of the pool, refill and if CYA is in the 40 ppm, go from there. The calc says once I get my CYA under control, then I need to add ~6 96oz jugs of bleach and 3 lbs of borax, no?
Anyone have any idea on the funky test result?
FC - 5
CC - 0
pH - 7.3
TA - 120
CH - 370
CYA - 140 at least!!
