A great pond filter is critical to maintain the health and vitality of any fish pond.  Koi ponds in particular need highly efficient and effective filtration and we believe the Ultima II filters provide that, and at a reasonably affordable price too! 

Listed below you'll find a variety of filter sizes that will work in very small ponds of 500 to 1,000 gallons all they way up to 30,000 gallons.  Simply choose the one that exceeds your pond's gallon size and be sure to take fish loads into consideration too.

A biological filter is the most effective and safe way to keep excess nutrients in check that come from fish waste.  Ammonia and nitrites, two things that are very toxic to fish are eliminated from the water with the help of the beneficial bacteria that's housed in these filters.  Plus water quality is maintained and problems like algae and dirty looking water are minimized too.

We prefer to use pressurized filters like the Ultima II because they are also easy to clean.  With a simple turning of a dial, you can be backwashing this filter in seconds and be done with this often dirty task quickly and easily, without ever getting your hands messy.

All in all, we haven't found a better filter at a better a price, so read on to learn more about the Ultima filters from Aqua Ultraviolet.
