This meter can measure the amount of oxygen present in a pond water sample. Another way to measure oxygen levels in a pond is to use a colorimetric test.

This test measures the amount of dissolved oxygen in a pond water sample.

How can I oxygenate my water without a pump?

Oxygenation of water can be done through various means including aeration, diffusion, and bubbling. Aeration is the most common means of oxygenation and involves the introduction of oxygen-containing air into the water.

Diffusion and bubbling are less common methods and involve the diffusion of oxygen gas or bubbles into the water.

Can you make a pond without a pump?

A pond can be created without a pump, but it will take more time and effort. The first step is to dig a hole large enough to fit the pump.

Can koi live in a natural pond?

There is some debate amongst koi keepers as to whether or not koi can live happily in a natural pond. Proponents of this lifestyle believe that the natural environment provides a more stimulating and enriching experience for the fish, while others maintain that the sheer size of most natural ponds can be too overwhelming for koi.

Ultimately, it is up to the individual koi keeper to decide whether or not to keep their fish in a natural pond. If you are interested in trying this lifestyle out, it is important to remember that there are a few key considerations that you will need to take into account.

First and foremost, make sure that your pond is large enough to accommodate your koi. Secondly, make sure that the pond is well-maintained and has a consistent water flow.

Finally, make sure that the pond is located in a temperate climate. If you are unable to meet any of these criteria, koi may not enjoy living in a natural pond and may be better off living in a traditional fish tank.


A koi pond does not necessarily need a pump, but it can be beneficial. A pump can help to circulate the water, which can oxygenate the water and help to keep the water clean.
