What is Hydro-Pure Technology?

Hydro-Pure Technology is a patented water detoxifying and depurating technology for applications in both Marine and freshwater Aquatic Hobby. It consists of two electro-plates to energize a cartridge box containing special Cata-Pure Catalyst Media to generate strong reactive Hydroxyl (OH•) radicals, which is the key to the detoxifying and depurating reactions process.

What are the three phases of Hydro-Pure technology?

Phase 1. Aquarium water containing Protein, Ammonia (NH3) and Nitrite (NO2-). 

Phase 2. Cata-pure Media reaction produces reactive Hydroxyl Radicals (•OH) from water. Hydroxyl Radicals (•OH) reduces Protein, toxic by-products like Ammonia (NH3), Nitrite (NO2-), and odour from Sulphur-based by-products.

Phase 3. Biologically clean and healthy water for fish and invertebrates.

How does Hydro-Pure Technology benefit my fish keeping experience?
  • Hydro-Pure Technology creates safe and stable pristine “Hydro-Pure Water” similar to that of natural river stream rich in micro nutrients and minerals.
  • Prevention of cloudy water by the ionization of solid precipitation present in the waters.
  • Minimizes unpleasant smell in the water caused by the oxidization of Sulphur-based products.
  • Minimizes frequency of water change thus saving time and enjoy greater savings on your utility bills.
  • Hydro-Pure Technology is suitable for marine and freshwater fish tanks of all sizes, all types of fishes, plants and live corals including all levels of stocking density.
  • It also helps in the prevention of New Tank Syndrome especially in Marine tanks application, perfect for any applications that requires pristine water condition of safe and stable level of Ammonia, nitrites and nitrates acceptable for aquatic life form.
