(Sponge/foam underneath, biomax on top and this in the middle.) My tank wasn't particularly cloudy or even dirty, but I was intrigued so I wanted to try this. Overnight the water clarity improved to an unbelievable level. I didn't realize it could get this sparkly! I'm including a video to share how clear it is, especially looking into the tank from the side! I've had an aquarium for over 20 years. I absolutely recommend this and will use it from now on.
