Let me start by saying I tend to over-think most things, and how to apply stabilizer has driven me nuts for the 4 years we've had this vinyl pool. Tried socks, hose, skimmer basket 'socks', slowly feeding into the skimmer (sans the basket). Today was the day, with a lot of help from my best friend, my wife.
The problem in all methods has always been the same, how to dissolve the the darn stuff. Won't go into all the things that that don't work and take forever. This solution works, is easy, safe, and fast.
First, I did put a skimmer sock in the skimmer to act as the final filter.
Then in a blender, I put 3 cups of tap-hot water.
I put the top on and start on lowest speed. Then remove the top.
Slowly add 1 cup of stabilizer. Put the top back on.
Crank it up to highest setting and let it work for a while. It will become somewhat milky in texture.
Turn it off and pour it into the skimmer basket, which has the skimmer sock in it.
It doesn't take long to be processed and ready for the next batch.
