Air Pumps

Probably one of the most important piece's of your Pond & Filtration equipment is the 'Air Pump' which provides sufficient air to both the pond and the filtration units themselves..... a pond, or tank, without a sufficient air supply for the Koi and other pond fish is like a time bomb waiting to go off !

You will probably get away with it for a few years and then you will try to figure out the reason for your Koi dying with no visible signs or marks on them ... this can, and more than likely will be due to the oxygen level being far below what your pond life requires ... We are often told 'Oh we don't need an air pump - we have oxygenating plants' ... well yes OK - these plants will generate a certain amount of oxygen during the evening .. but come the hot day time and they will take all the oxygen they can out of the warmer water .. leaving very little for your Koi when it may be noticed that they are gathering around the bottom of a water fall or near to a Venturi .... a sure sign that they are having difficulty in breathing.

To provide air in the quantities you need you are really going to need an efficient pump .... there are not many on the market that have enough output air pressure in sufficient quantities to power, say 6 x 2" air stones or diffusers, or even a diffuser drain which are now becoming very popular - especially at the time of a new pond construction or a major re-build. The Air Pumps we list on our pages will accomplish all these tasks - whether your pond is just 1,000 gallons or 100,000 gallons !

Important notes about Koi Pond Air Pumps:

If you are deploying an Air Pump to generate the Air for your system .. we do advise that the air pump is located as near as possible to the outside Fresh Air .. where there can be no danger of the Air Pump drawing in bad smells, or fumes, which will then quite possibly severely affect the quality of the air that you are providing for your system ... which could, and has been known to cause problems for the pond life, and it is extremely hard to identify the source of this problem with the air supply in 99% of the cases never being suspected ...  so remember that prevention is better than cure ..

At the moment we can offer three manufactured brands of efficient Air Pumps ... the first is probably the best known of the two and is the 'HI BLOW' - the other a NEW One is the - 'Nitto Kohki's MEDO BRAND' and the last one is the 'SECOH' which we believe is probably the best diaphragm model available on the market today - with those hard to find Spares, being readily available for every model in the range ..

Unlike the Hi-Blow and Secoh range - the Medo Brand are piston driven - both of these are of Japanese Origin and are fully guaranteed against defects for a full 12 months ...
