Filtration Equipment
Aerator stone in a lake ( aquapic)


In addition to pumps and filters, we supply and install airpumps, skimmers, UVs and a range of other useful equipment for ponds.

The lake shown on the left is aerated by a quiet and efficient airpump, sited remotely. The steady stream of airbubbles benefit the fish with extra oxygen in the summer months. Aeration can also improve conditions in stagnant or sediment-laden waters.

A surface skimmer (below) can help remove floating debris and duckweed. It also promotes sparkling clarity of the water surface in reflecting ponds, koi pools, and swimming ponds.

UV (ULTRA VIOLET) UNITS are part of the armoury to control green-water algae and are often used in conjunction with other forms of filtration.

These safely and efficiently aid water clarity without the need for chemicals.

We install and provide annual servicing of UV units - acid-cleaning of quartz sleeves; lamp and seal replacements.

Multiple UV units can be plumbed together to suit larger ponds and lakes. Newer units incorporate multiple, long-life lamps, with anti-fouling quartz sleeves and electronic management, for optimal control of green water algae whilst reducing electrical consumption.

SIEVE UNITS remove large debris and suspended scum from koi ponds and swimming ponds and are often used as a pre-filter before other types of filter.

DOSING DEVICES add a constant low level of copper or chlorine/bromine to the water, helpful where control of stubborn algae is necessary.

We prefer natural options wherever possible, but these units are an alternative e.g. in fountain features where there are no plants and fish.
