This is some good stuff. My recommendation is that you knead it longer than I did the first couple times. It comes with a green stick of puddy and a purple. The longer you knead it the quicker it sets up and the color is a deeper purple more resembling coraline algae and not a clump of puddy in your tank. Resealable container so you can cut off what you need and not worry it will dry out. Does break down a little meaning it fogs the salt water slightly but the protein skimmer takes care of all that pretty quickly.
