The pompons are from Oriental Trading. They are lower quality than the green poly shakers but are 1/2 the price. I have them all floating in a tub of fresh water to see how they saturate. So far it might take a while, or a wash with soap to get them fully submerged and more weight maybe needed. The smallest sinking model will work great in a spawning tub, or for a squeeze media.

Feed the zip tie through the insulator then around the pompon, back through the insulator and zip the tie
The mechanism of the tie keeps it from falling through the insulator
The cut end of the zip tie is very sharp
Melt it with a lighter to save your buckles and the fish's scales
