The Aqua Ultima II Filters are known in the industry as the easiest filter to maintain, the Ultima II Filters take just 5 minutes a week to backwash. Gone are the days of dismantling your filter and scrubbing pads. The Ultima II Bio-mechanical filter traps and converts fish waste, ammonia, into a substance that is harmless to fish called nitrates. Nitrates can then be used by the plants in the pond. If Ammonia is left untreated, it can cause serious harm to the Fish. The Ultima II bio-mechanical filter creates an ecosystem for your pond, replicating the natural, beneficial bacteria found in ponds and lakes, ensuring a healthy environment for your fish. How is the Ultima II Different? The key is the patented media which is exclusive to Aqua Ultraviolet. The Aqua Ultraviolet media traps solid waste while also providing a protected growth surface for beneficial bacteria. This biofilm is what converts the ammonia to harmless compounds. Because of the innovative design, the filter media has the most biofilm surface area of any in the industry. One square foot of the Aqua UV filter media has 800 cubic feet of surface area! This media never needs to be replaced and requires no maintenance, just backwash weekly. The Ultima II filters are sturdy, durable units made from heavy-duty material. The Ultima can even be buried up to the valve assembly for concealment if desired.
Match Your Filter with the Right Pond Pump
To get the best results, your pond filter must be paired with a properly sized pond pump. Choosing the correct pump ensures adequate flow rate and head pressure, which are both critical for effective filtration.
Find the Ideal Flow Rate
Each Ultima II Filter model has a recommended flow range. For example, the Aqua Ultima II 10,000 Filter performs best with a pump that moves 5,000 to 7,500 gallons per hour at 10 feet of head pressure. Always check the specs for your specific filter.
Improve Energy Efficiency
Opt for an energy-efficient pond pump. Not only will this save you money on electricity, but it will also reduce wear on your system. As a result, your setup will run longer and more efficiently.
Boost Your Water Quality
When your filter and pump are working in harmony, the water quality improves dramatically. Fish stay healthy, algae is reduced, and your pond becomes easier to maintain.
