Adding Cyuranic Acid to Sand Filter?

[JimK]

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).
