Overview

20,000L 18W Clear Control Pond Filter

This Clear Control Pressure Filter is a hassle free premium filter system designed to maintain a healthy biological equilibrium in your garden pond, keeping the water clean, healthy and clear. The filter includes lava stone, activated carbon and Japanese matting, which are able to remove large amounts of dirt particles and bacteria, while a Dirt Indicator uses a traffic light system to helpfully indicate the extent of the contamination inside the filter. The filter also includes a series of useful additional functions: medication can be delivered into the water, and the pond can be drained if the need arises. An included Ultra Violet Clarifier also helps keep green water algae under control.

Please note: A pump is not included and should be purchased separately.

Tips on Installation and Maintenance

A lot of water features come pre-assembled for the most part, with just a little hose/pump connecting to do before plugging it in to a solar panel or mains socket. Some of our bigger ones require wiring in a plug (which might involve a Part P Certified electrician), but otherwise all instructions will be included.

If you've got any questions, why not check out our Installation Guide for tipson installation location, power and even style tips!
