Here are my results. (i have a 25k gallon IG concrete (i think) pool)

FC-0 (as expected)
TC-0 (as expected)
CC-0 (as expected)
PH-8.0
Alk-60 ppm
CYA- >30 (i had to fill the tester thing all the way to the top and I could still see the dot. I believe I have zero because I refilled the pool last year and used only bleach all season. I was wondering why my chlorine wouldnt remain steady, but now i know the reason)

First thing I did was clean my DE filter, put it back together and put 6 pounds of DE through the skimmer.

Then I bought a five pound bottle of CYA and put the whole thing in.

What should I do next? (chlorine first or adjust the ph)
