It is possible, but a fish pond needs oxygen for the fish to survive. As oxygen levels are so vital to the wellbeing of your fish, a bubble stone or waterfall will also help to bring oxygen to your pond. It is possible to keep a fish pond without a filter, with regular doses of Aquaplancton.

Also, does a fish pond need a filter? No. If you are intending not to have any fish, or you're creating a wildlife pond with high plant stocks and just a few fish you may choose not to have a filter, and try to create a natural balance instead. You will need plenty of plants, probably covering two thirds of the pond area.

Do all ponds need a pump?

Pond fish depend on pumps both to filter their excrement from the water and to keep the level of dissolved oxygen in the pond water at a suitable level. Fish may live for a short time in a small pond without a pump, but will quickly run in to problems unless the water is frequently changed.

Yes a pond can hold water without a pond liner. Since shallow ponds of a couple feet experience less head pressure from the water, they may not require a dedicated liner. What they do require is dense silt soil that is well compacted.

How many goldfish can I put in my pond?

A second rule is to have 1 square foot of surface area per inch of fish and 10 square feet of surface area for 1 koi. So, as an example, if you have a pond that has a capacity of 2000 gallons, you can hold 57 inches of koi fish (5 domestic koi fish) and 100 inches of goldfish (25 common goldfish).

Do pond pumps use a lot of electricity?

Pond pumps have become much more efficient over the past twenty years, but a fair amount of power will always be required to move substantial volumes of water. As a guide, electric costs for: A small spouting frog ornament --- 5p per day. The very smallest in-pond filter/UV system --- 8.5p per day.

How do I raise the oxygen level in my pond?

Add a Pond Air Pump
A very simple way to add oxygen to the pond is to add an air pump. Sitting at the side of the pond, it will pump air through a small hose to an air stone and bubbles will enter the water. When the bubbles break the water's surface oxygen will then be added.

How do I know if there is enough oxygen in my pond?

One of the most common signs of stress to look out for is fish gasping for air at the surface of the pond water. Although it generally depends on the state and size of any individual pond, its best to have at least 6mg per litre of dissolved oxygen in any body of pond water.

Can you over oxygenate a fish pond?

But the real answer is yes, there is a point when you have TOO much oxygen in the water. It's called hyper-saturation. Rarely does it happen, but it can. If you hold your hand under water up to your elbow, and see small bubbles develop over your sking, you have too much.

UV pond filters kill algae and bacteria, which means you need an additional filter to get it out of the water. Additionally, a pond UV light filter will not help to get rid of string algae, which does not travel in the water column and is therefore not exposed to the UV light.
