Test results:
FAC 1
TAC 1
Salt 2900
CYA 0
TAC 80
pH 7.4

My question is this, can I really have NO Cyanuric Acid? I was under the impression that this never went away. The reason I'm here asking is because a buddy of mine got burned by adding to much to his pool and he said he had to drain it, something I obviously want to avoid.

The pool is one year old, saltwater, in-ground, and approx 17,500 gallons. When I tested in the fall I had my CYA was 50. The pool is in Texas so I didn't drain it over the winter or anything.

Obviously the chlorine measurements are a bit low, which would be explained by absence of CYA. The pool calculator said I need to add nearly 2 gallons of liquid stabilizer ~240oz was the result I believe. Anyway, do I really need to add that much CYA? As for the pool, its freaking sparkling right now, couldn't be happier. Anyway, eagerly awaiting advice on CYA.
