Koi Fish Pond & the Aeration

It is important to conduct oxygen level testing for the koi fish pond, in order to be assured of the enough aeration in the koi fish pond. Enough aeration in turn is needed to completely support the fish and the plant population in the koi fish pond. This testing should be done at the time of establishment of the koi fish pond or at the time of putting some new fishes in the pond. Once you have made sure that the oxygen level of the pond is quite satisfactory there is no need to be worried about the aeration unless you have a pump, which is broken.
