AllPondSolutions range of automatic pressurised pond filters with built-in UV clarifiers are designed to be efficient self-cleaning units with the simple turn of a dial. Just like the manual PFC models, PRO filters are kept continually pressurised by your pond pump which will help you to maintain the best water quality for healthy pond fishkeeping. The PRO range features a built-in UV light timer, ensuring the UV clarifier operates efficiently during peak times, effectively targeting algae and harmful microorganisms that can affect pond health. Pond filter cleaning with PRO range is easier than ever due to the motorised sponge cleaning system. Just turn the dial so that the blue arrow is pointing in the direction of the dirty water outlet; listen for the beep indicating the start of the cleaning process and at the sound of the second beep your PRO pond filter unit and sponges will be clean. Not only will this reduce the need for any manual labour but there is no need to disassemble any part of the unit except when replacing foams or performing a full system clean. Each automatic cleaning PRO pond filter is equipped with a built-in UV light, which helps prevent algae growth and eliminates micro-organisms in the pond water which can lead to fish diseases.
