When adding CYA, use the "sock method." Using cut nylon legs or nylon knees highs is much quicker.

From Pool School:

Solid/granular cyanuric acid (CYA) should be placed in a sock and the sock put in the skimmer basket or suspended in front of a pool return. After adding CYA you should leave the pump running for 24 hours and not backwash/clean the filter for a week. Squeezing the sock periodically will help it to dissolve faster. Test and dose chemicals in your pool assuming the amount of CYA added is in the pool according to Pool Math. CYA can be tested the day after it is fully dissolved from the sock.
