Once the CYA is there, it is only goes by water loss or reverse osmosis. So the issue with tablets, is that unless you plan to change the water ever season, it won't be seasonal in terms of CYA level. And you end up getting into a problem of chasing a good free chlorine level. Because as CYA increases, you need a higher FC level, so you need to add pucks more often, which increase CYA more quickly, requiring you add even more pucks, ....
Do not use "low splash" or "scented" chlorine as these have things in it you do not want.
So there are options.
1) pour it into a bucket first, down the side, tilted, (not used for other things!!! this is important) and so when you pour in pool (or just lower into pool), should come out slower - or you can slight water down first.
If you really don't want to deal with it then other options:
2) get a liquid chlorine injection system ($$)
or
3) get a salt water chlorine generator ($$)
