I just found this site prior to putting my first pool in. So awesome finding all this info. The pool is a 24' abg and 48" deep so roughly I figured 13000 gallons. I placed 4 lbs of CYA into a sock and let it dissolve into the pool in front of my return 6 days ago. I have tested yesterday for CYA and the test only read 20. I know that I was like 4 oz short of CYA to have a reading of 40 but wouldn't it have shown up closer to full reading by now? My daily fc loss is between 3-4 everyday due to the pool getting anywhere from 12-14 hrs of sunlight directly. I had placed in 2 7oz trichlor pucks to add just a little bit of CYA at a time (don't plan on using them in the future, but since I had them thought what the heck).
I'm at work but I'm pretty sure my numbers are as follows:
FC: is normally 4 when I check every night ( I raise to 7 after testing)
CH: Never checked since vinyl pool
CYA: only reads 20
So should I wait and just see if I CYA goes up in the next few days or should I make a trip in and buy more stabilizer? We are having our first pool party tomorrow night so I am planning to dose heavy tonight on the bleach and then again on Sunday when I get up in the morning. Anything else I need to look at doing in regards to the pool chemistry? It looks awesome right now all sparkling and clear, but don't want to mess anything up.
