Will CYA granules on bottom of vinyl pool cause problem?

[aylad]

I always add cya slowly directly into skimmer with pump basket removed. This seems to work fine. Any problems with this method that I am not aware of?

That's the method that I use, as well. Just make sure you're pouring it in at a slow enough rate that it doesn't clump up in the pipes before it gets to your filter.

also remember not to backwash your filter for a week or so after the CYA addition to keep from washing it right back out.

I just did this by taking the cya and a bucket of water and mixed until the water was thicker then added it through the slowly thorugh the skimmer. There was alot left in the bucket but I just repeated it until most was dissolved then I just scooped the rest in the skimmer slowly. I wish I would have read about the nylon first.

What you did was fine. I have always added my cya directly to my skimmer and have never had a problem. Just remember not to backwash for a week or so or you will just backwash the cya right out.
