Not long term. Almost all pucks are TRi-chlor, meaning they contain CYA. That CYA will build up in your pool over time unless you change out the water. Eventually the high CYA will drive your needed FC level to an unsustainable level. Pucks are good for vacation, or if you need to add CYA to your pool (i.e lower level after a big rainstorm). Otherwise, not normally advised.
