Boyd Enterprises Chemi-Pure Blue Filtration Media for Aquarium, 11-Ounce (2 Pack)

Keeps my 20 gallon with no skimmer clean

Definitely recommend for any filtration system!

Typical chemi pure quality. The extra ingredients they used in this blue work well. I have seen a decrease in phosphate and NO3 in testing. Im using two in a 55 gallon reef with a 30 gallon sump. I also have a protein skimmer in the sump. Water has been crystal clear. I recommend using this product even if doing RO/DI water. I have used Chemi pure since its came out. Its the best for keeping water clean and clear. Plus being in bags no issues of spilling trying to fill filter and changing monthly. I change mine once every three months. I would recommend this product to anyone.

The best media on the market. Crystal clear tank.

This product was a clear saver. It made the aquarium water crystal clear and was safe for the fish. It made the water so clear it looks as if there is no water in the tank and the fish are just floating around in air.

excellent product. in only one hour the thank looked a lot cleaner.
