Adding Cyuranic Acid to Sand Filter?

I always just pour mine slowly into the skimmer and never have a problem. Alternately, you can put it in an old sock and hang it in front of a return jet. If you give it a squeeze once in awhile, it will help it dissolve faster.

I also just add it slowly directly into the skimmer and have never had a problems (pool installed in 2004).

Ive found a good method that seems to work quickly.

I take a mens dress sock (shh my wife doesnt know) and fill with the cya you want to add. I take the top off my skimmer and feed the top of the sock thru the hole in the skimmer top. While holding the top of the sock, I put the top back on the skimmer to measure how long I need the sock to be to be in the flow of water, then tie a nice knot.

Takes about a day to go through 1.5lbs of conditioner this way. No need to squeeze or mess with it and easy to check.

That's kinda the way I added my CYA this spring. Put it in an old sock and laid the sock in the skimmer basket and then kept the pump running 24/7 until it was gone.

and then kept the pump running 24/7 until it was gone.

If you run the pump 24/7 it doesn't matter much how you add it. It will usually dissolve in about 48 hours (or at least enough of it to protect your chlorine) I just pour it SLOWLY into the skimmer with the pump running. It's the easiest way.
