AG Pool - 8,500 - sand filter

FC: 2.0
PH: 7.5
ALK: 110
CYA: 50

We have been trying to "stabilize" the pool for three days now coming out of our "shock treatment". I'm already running out of some of my drops from my 6 way... can you buy the drops separately, especial the CYA... Don't have enough for another test.
