Api-Pond Aquatic Plant Media

I’ve used this planting media for years in my pond, but since the pandemic it has been impossible to find. It doesn’t cloud the waters. The fish can sometimes pull the plants out of this soil, so I usually will put a layer of small 1/4 to 1/2 inch stones on the top of the container.It still seems impossible to find since the Amazon vendor sent me the wrong product —- plant tabs instead of planting media. Plus the larger 25# bag would be much more cost effective, but can’t find anywhere.
