I had a problem in my fish tank where the water seemed not dirty but just a bit cloudy. I headed over to petsmart and they recommended the eheim ehfisubstrat and let me tell you, it works great!! Within a couple hours i had never seen my tank that clear before, and my fish seem to love it too. Would recommend to all! BUY THIS STUFF IT REALLY WORKS
