Creating a Stable and Safe Environment. For Marine and Freshwater aquarium

The natural beauty of an aquarium creates fun and excitement in your living space. However successful fish-keeping requires the aquatic hobbyist to understand basic fish-keeping principles and to conduct regular aquarium maintenance. Poor water quality is every aquatic hobbyist’s worst nightmare, as unfavorable water conditions (i.e, high ammonia levels, excessive nutrients) could potentially stress and kill your aquarium inhabitants. 

OF® Hydra Aquatic Depurator, powered by Qian Hu’s patented Hydro-Pure Technology, produces Hydroxyl radicals (•OH) which effectively detoxifies harmful Ammonia and many other toxic ions to transform poor quality water conditions into a safe and stable living environment for aquatic life forms to thrive-in.
