As long as you are aware of what the CYA is throughout the season and adjust your FC accordingly, you are OK. See the post below yours for how much CYA pucks can add.

When we went on vacation a couple of years ago (for 2 weeks), I left 4 floaters wide open, each with 4 pucks in a 20,000 gal pool. I'd say about 10-12 of the pucks had dissolved, and my CYA shot from 30ppm to 65ppm. My pH was at 6.8 (which means less) and it took 4 boxes of Borax to get it back to normal. That means each puck was adding 2-3ppm of CYA to my 20,000 gallons.

Something to think about.
