I tried searching and must just be blind! But what is the reason to add cya in a sock vs. just straight into the skimmer like is recommended on the package?
Why add CYA in a sock?
- Thread starter eldender
- Start date
When added to the skimmer you cannot clean your filter for a week to try to make sure all of the CYA gets dissolved. There is also no way to confirm when it is completely dissolved when it is in the filter, whereas you can when it is in a sock. And we also discourage adding any chemicals, especially solid ones, directly in to the skimmer. More than a few people have arrived here looking for help after adding CYA to their skimmer and watching it get completely clogged up.
We recomend adding CYA by using what we call the sock method.
Get an old sock (no holes in the toes) and put the measured amount of CYA you need to get to your first target. Tie the sock closed and either suspend it in front of a return (hang it from your brush pole works with something weighted on the deck) OR if it still allows flow thru the skimmer, place the sock in the skimmer. Every 15/20 minutes give the sock a squeeze to speed up the process or just leave it alone, your choice. Please DO NOT follow the directions on the container of CYA to just pour it into the skimmer and don't just toss the sock in the pool as the CYA is acidic and can bleach/stain pool finishes.
We also like to see folks add chemicals like CYA in stages.
Why?
Well, for those with a sand or DE filter the CYA will become trapped in the filter and you will not be able to backwash until it's gone. When will that be? Who knows, you can't see it anymore.
In your case it will get stuck in the pleats of your filter cartridge.
Witht he sock we can suspend it in the water and give it a squeeze every so often to speed up the dissolving. Plus, CYA is acidic, and suspended in teh water away form all surfases means we can't accdentally damage or bleach a surface.

Thank you! I usually have a good reason when explaining but on this one I just kept saying “that’s what tfp says so you have to!” Haha

When added directly to the skimmer it has been shown to accumulate, undissolved, in the filter, for quite some time. Best bet is in a filter sock, in the skimmer basket, wait 20 minutes for it to be totally saturated, then squeeze it all out.

Skimmer line blocked with stabilizer
I was trying to raise the CYA and added about 2.5 Lbs. stabilizer down the skimmer. I guess I did not do it slow enough and now the skimmer line is completely blocked. There is no suction at all from the skimmer. If I set the pump to skimmer-only, the pump does not suck any water. How do I...
