Anjon LivingPonds 4000 Pressure Filter w/Mats & Bio-Balls

The Anjon BioPro Filter with high-output UV clarifier filters ponds up to 4,000 gallons, providing optimum water conditions and crystal-clear water. Two unique options are available - with filter mats and bio-balls, or only filter mats. Filter pads will physically trap debris while bio-balls promote the growth of beneficial bacteria.
