OK, I went to Walmart and the only product I could find that had cyanuric acid in it was a 4lb bag of "hth 3-in-1 startup" for salt pools. The ingredients list is as follows:
1,3,5-TRIAZINE-2,4,6(1H,3H,5H)-TRIONE (Cyanuric acid) 77%
Hexametaphosphate - 17%
Aluminum Sulfate - 5%
MAGNESIUM CARBONATE - 1%

I also got the @0 Mule Team Borax and have the liquid bleach for shock. However, I did see some straight trichlor shock, but I didn't buy it yet.

The readings are: TC: 1-2, pH: 7.2, TA: 290, TH: 360, CYA: still see the eye clearly.

Any suggestions?
