Hello everyone,

Since we purchased our house I have been working on this pool daily. It has probably been a little over 3 weeks of constant work on it, chlorine, scrubbing, raking, etc. The pool is still green and I still can't see the bottom.

I purchased a test kit and have been testing the water and getting my levels to where I need them. I took a sample into our local pool store and they had quite a few different readings than what I got.

Pool Store:

FC = 3
TC = 5
PH = 8.0
TA = 140
CYA = 100
CH = 170
TDS = 850

He didn't test metals like I asked, so will be going back but somewhere else this time. Anyways here is what I have for my readings.

FC = 19
CC = 1
TC = 20 ???
PH = 7.7
TA = 160
CYA = 65
CH = 180
TDS = ?

We are currently shocking the pool like crazy, which is why his FC of 3 is very weird. We took our reading about 1 hour after we took in the sample in to the store. We had shocked before we took the sample in to the store. This will be day 4 for us of keeping the FC >= 20, and the pool is still not clearing at all.

I see that our CYA is a bit high which is odd, because we filled the pool about 3 weeks ago, it was about half full.

It is a 25,000 gallon vinyl lined pool. We are currently using bleach as our form of shock. Any help would be greatly appreciated.
