The other 32% of the puck is what you need to worry about. It's stabilizer (CYA) that stabilizes the solid form and in your pool, acts as sunblock for the chlorine. Some CYA in your pool is good 30-60 PPM is common, and desirable. When it gets to 100-200 PPM or more, it bonds with your chlorine to the point where your chlorine does nothing to sanitize the water.... and algae is nearly uncontrollable. The stabilizer also collects in the pool, every puck you add, and adds more CYA that never really goes away. You need to remove water to get rid of it. Some pucks/sticks/tabs also add calcium, and in some pools, too much calcium is an issue.
Liquid chlorine is 6-12.5% chlorine with the balance (87-94%) being water (and a tiny bit of salt). The water does nothing adverse in thine pool and salt is so minor it's normally not even mentioned.\
