Having a higher CYA does allow you to go longer between testing and adding doses of bleach. There are several here on the forum who deliberately run a higher CYA pool for this very reason.

You can definitely add straight CYA to your pool. I usually do so myself. In a pool your size, each pound of granular CYA will increase your level by about 10ppm. There are several ways to add it. One way is to just pour it slowly into the skimmer while the pump is running and then keep your pump running about 4 or 5 days after you add it to let it dissolve in your filter. But, with a cartridge filter, that might not be the best way. You might just want to put it in an old sock and hang it in front of your return jet. Every once in awhile, give the sock a squeeze to help it dissolve faster. That is probably the best way for you to add it. (The directions on some containers actually tell you to just broadcast it across the pool, but don't do that.)

Oooops! I did some searching while I was waiting for a reply and several other threads said to just put it in the skimmer, so I already added about a pound and a half. I didn't see any warnings about cartridge filter systems. What will it do to my cartridges??? Do I need to shut down and clean them off immediately?

Probably nothing but let me ask Ben about it. Sit tight.

It won't hurt your cartridges . . . but do NOT add chlorine, especially cal hypo, to the skimmer for at least a week. Longer, if you're pump is on a timer.

Okay, I don't ever put chlorine in the skimmer. I currently have trichlor tabs in the auto chlorinator, and also in a floater in the pool. The floater does tend to congregate right at the skimmer opening. Is that okay?

[PoolDoc]

That's fine.

So is there something about concentrated chlorine coming into contact with CYA that can be a problem? Are we trying to avoid some type of reaction?
