Why do we need air in our koi ponds?
An adequate Oxygen supply is vital for
the health of our koi. All forms of life need and consume oxygen.
This is the same in our koi ponds and plants (including all forms of
algae) , organic life and of course our koi consume oxygen. Koi are
rather special in that they need a considerable supply of oxygen in the
water for their survival and well being.
In fact they need a minimum of
6mg/litre of oxygen dissolved in the pond water. .Our filter bacteria
(and in fact all aerobic bacteria) also consume prolific amounts of oxygen
which they use to oxidise Ammonia and convert this into Nitrite and then
convert Nitrite into Nitrate. Filters will not work properly without
an adequate oxygen supply within the media.
Decaying organic matter also uses
oxygen as it is converted into waste and the 'dirtier' the pond, the
higher the requirement for oxygen.
|
 |
|
Plant life consumes oxygen during the
night and gives off carbon dioxide. This process is reversed during
the day. The more organic load on the pond (fish, plants, decaying
material) the higher the biological oxygen demand (BOD) Every life form is
therefore competing for oxygen.
Cold water can hold considerable amounts
of dissolved oxygen. Unfortunately, during warm weather, the ability
of water to hold dissolved oxygen is substantially reduced and during warm
muggy, thundery days in summer, there is a real threat to the health of our
koi, especially overnight, when plant life can quickly strip the
already low levels of oxygen from the water with fatal results for our koi.
It is therefore vital to top up our
dissolved oxygen supply to ensure the health of our koi and to ensure our
filters continue to operate correctly. Oxygen can be supplied by waterfalls,
venturis and air pumps. Waterfalls are extremely efficient at
providing good aeration, but many ponds just don't have them, and even
where present, many people turn them off at night, just when they are needed
most. Venturis are extremely inefficient devices, only work near the
surface and use a considerable amount of pump power to run, thus making the
pond water pump work harder than it needs to in order to deliver the correct
amount of water.
Without doubt air pumps are the most
efficient and cost effective way of providing adequate aeration to your koi
systems and we are pleased to be able to offer the best air pumps available
today from the Secoh range. |
