Aqua Ultraviolet’s UV Sterilizers have been used by public aquariums, importers and hobbyists alike to control bacteria, protozoa and parasites, reducing the spread of fish disease. In a confined environment like an aquarium UV and filtration are essential.

 A UV Sterilizer is a proven method to eradicate bacteria, viruses and protozoa.

The Ultima II’s patented design does the work of two filters, removing debris and nitrifying ammonia produced by aquatic life; simply backwash once a week.

We will even help you choose the UV and Ultima Filter for your aquarium
