When you need pucks, floaters are dirt cheap--an adjustable one is about $10.
I can think of a few reasons off the top of my head:
- You already have in-lin chlorinator and would rather spend $10 on the nectar of the gods (brown liquor) than on a floater.
- You have small children are are worried about the potential safety problems that might arise when those small children and a floater get together.
- You are more concerned with asthetics than most and don't like the fashion statement a floater makes.
- You are a new pool owner who didn't know about floaters when the pool was built and you went with the builder's recommendation. This one brings us back to the first case, especially the brown liquor part as you probably need it after the bad pool building experience you just survived.
- The fact that the chlorine is distributed in the water more quickly and evenly with an in-lin chlorinator as opposed to a passive floater appeals to your anal retentiveness.
