Our community has rated this post as helpful. If you agree, why not thank

This is good timing for me, and the price is right.
Just a reminder, use the pucks with stabilizer only to start your pool.
Once your CYA (stabilizer) is where you want it, STOP! NO MORE!
Use liquid chlorine (bleach) or a salt-water generator after that.

These are great. for a quick hitter, i fill with 1" pucks and drop in the skimmer. The rush of water dissolves them faster if I don't want to add chlorine right away like visitors, etc.. I then drop it in the pool and let it float away...

You might want to rethink that strategy...
'You should not put chlorine tablets in a floater inside your skimmer basket. Doing so exposes your pool pump, filter, heater, and rubber seals to highly concentrated, acidic water—especially when the pool pump is turned off and the water stops moving. This can corrode your equipment and degrade plastic or metal parts over time'.

Correct, you should never put chemicals directly into the skimmer unless you want your equipment to eventually fail. Ask me how I know.....

Found this out the hard way after it got too cold for the SWG to work. I didn't think a puck put in nearly as much CYA as they did. Probably gonna switch to low dose shock for treatment over winter months.
