Cannot raise CYA

[QiingGuy]

@Watermom - I HAVE NOT ADDED TODAY'S APPLICATION YET and will hold off until I receive further expert advice.

I added the original 2 lbs on June 19, 2014. The follow-up HTC application was done on July 5, 2014. ADDITIONAL INFORMATION: Either a couple of days prior to or after I did the HTC application I needed to add a cup of Klean Strip Green Muriatic acid to lower my pH. Don't know if this could effect my CYA level or not but thought I'd throw it out there just to be safe.

The original application was dissolved in a 5 gallon bucket and added to the pool (this application got me to 30). Second application was done in sock hanging off the side near in-let or out-let forget terminology (water coming into pool). I have approximately .3 lbs left in sock. It appears the second application has not raised CYA at all.

Source is from hose/city water. Why drain, I'm 50 ppm from where I need to be. Confused . . .

EDIT: One last thing, I've done three separate tests. One my own, and two at separate Leslie's locations.
