Water Purifier Cube with Activated Carbon Block for Livestock Troughs and Aquarium Algae Control
-
Cloudy, algae-filled water clears fast: fish tank algae control that purifies the water so it is safe for fish and pets to drink
-
No wiring, no plumbing: the cube drops in and its airtight seal needs no continuous fresh air pump
-
A whole trough in one drop: each cube treats up to 40 gallons
-
Murk and odors out of the tank: aquarium water treatment that filters out dirt, cloudiness, odors and pathogens

Clean water on a budget: the eco-friendly cube saves you money
Murky, algae-filled water in a trough or tank is no one's idea of a drink for fish, pets or farm animals. Drop this water purifier cube into the water and it is purified instantly, so the water is safe for them to drink. There is nothing to wire up and nothing to plumb in: the cube sits straight in the tank.

The core is a honeycomb activated carbon block with 99.6% ultra-absorption, which absorbs contaminants and improves the water your animals drink. It works as an aquarium algae remover, quickly removing algae, bacteria, parasites and other unwanted organisms. The energy-free biological filter self-sterilizes at room temperature and is rich in polyphenols and trace elements. Use it in paddocks, barns and tractors, as well as aquariums and horse troughs; as with any water additive, keep an eye on animals around freshly treated tanks.
