Save it, maybe you'll start another tank in the future, you never know.
I also add root tabs to my soil. JBL (German company I think) sells these mud balls full of nutrients, my plants do very well. If you have access to worm castings, you can probably freeze them in ice cube trays then push them into the substrate.
