I bought a house with a 24' above ground pool, that was looking pretty gross. I added some shock and got it from brown to green. I recently realized that the people at the pool store were basically guessing at how to fix my problem. They told me to add liquid shock per instructions till it cleared, but after reading up and finding this site ive realized ive been going about it all wrong and I need to superchlorinate it.
However, I dont have a good test kit. I just ordered the TF100 right now, but it'll take a few days to get here so I dont know what my CYA is right now. Ive been adding 1/2 gals of the liquid shock (blue shield shock treatment) every other day for the last week, and we added 1 chlorine tablet a few days ago in desperation.
I was going to chlorinate the pool with the "blue shield shock treatment" since it appears its just 12% bleach and the local pool place has it for around $3.
So....should I wait till my test kit is here so I know what my CYA is, or just try to superchlorinate it "blind" and adjust as needed when my test kit gets here?
