TDS = 450
phosphates = .25
FC: Low. Should be around 3.
TC: Should be the same as FC or you have CC (not good)
pH: Low Should be between 7.3 and 7.8
Alk: a tad low, but OK Range is 180-125, but up to 180 is FINE in vinyl.
CH: Fine
CYA: Low. Need to get it to 30-50ppm
TDS: Irrelevant
Phosphates: Latest fad in garbage to sell you. Fix the OTHER stuff first. Only worry about phosphates when all the other stuff fails.
