Storing Clorox

My CYA is over a 100 but I don't want to drain until next year when I replace the liner.

With your high CYA, you don't want it to go higher... I would use bleach and save the pucks for vacations and after you lower CYA.

What are the adverse effects of a high CYA?

Mostly you will have to keep very high chlorine levels in your pool for the chlirine to be effective. CYA, while helping to keep the chlorine in your pool, also decreases it's effectiveness.
According to Ben's Best Guess table, you need a minimum FC reading of 8ppm, max of 15ppm, and shock at 25ppm.
As you continue to ues pucks, your CYA level will rise, and so should your FC.
