Hello again. Last year, my first as a pool owner, I had great success with the BBB method. I made the foolish decision to let the pool turn into a swamp over the winter, but I got it back to blue, if not clear, at the beginning of this season with bleach and some dichlor shock (I never got it to hold FC over night). I chose the dichlor because my CYA dropped to zero. Zero CYA is the hallmark of my pool frustrations this season.
I added 8 pounds of dry stabilizer (purchased at Lowe's) along with many pounds of dichlor, and now probably 20 or so trichlor pucks, all in an effort to get some CYA in the water. My tests keep reading zero. I would like to get my sparkling clear pool back, but I'm not sure where to begin when I probably need to shock but I can't get any CYA into the pool.
Any thoughts about what could be wrong? I've considered that it could be my test kits, both of which are over a year old, but I have no idea about their shelf life. I've read around and seen that it could be some horrendous and unidentified bacteria (or maybe ammonia?) in my pool that will take an Olympian volume of chlorine to clear. I'm considering draining and refilling the pool, which costs around $250, if I recall rightly, instead of buying and lugging 100s of bottles of bleach.
Here is a current set of readings, assuming the test kit is not kaput:
pH 8.2 (or more?)
CYA below 30 (0?)
As always, thanks for your help.
