I have it fully submerged in my tank and it has been doing wonders. NO3 went from 10 plus to 2 ppm in less than 2 weeks. These blocks are embedded with sulfur hence the dramatic reduction in NO3. I got another one coming from JL aquatics as they will be carrying it. Great product, would recommend anyone who has trouble keeping their NO3 down to give it a try.
