Video: Reservoirs (ponds) With Fish
1. What type of reservoir (pond) is better? There are many options on the market, ranging from plastic or wooden ponds with plastic linings to concrete ponds with tiled surfaces. Some pond owners use mud, they put it on the bottom of wooden or concrete ponds to make the pond more organic. In terms of volume, reservoirs are also very different from each other, the volume varies from 10 liters to several thousand.
Let's assume that you have at your disposal a plastic reservoir with a capacity of 200 - 250 liters, or let's say a wooden one with a plastic gasket.
2. How to start the reservoir? Most likely the reservoir was already sold with instructions. Read it carefully and follow all directions. You may read that you need to add a water conditioner to get rid of the chemicals that are added to your tap water. Be patient. Fill the pond with running water, add conditioner, and wait at least three days before adding fish.
You will also need floating food for goldfish, such as TetraFin fish food for small fish and Tetra Pond Floating Food Sticks for large ones. Get a net (20 cm in diameter) with a handle long enough to reach anywhere in the water.
3. Choosing the right place. You can place the pond wherever you like, but you should avoid areas with a lot of fallen leaves and organic debris. Alternatively, you can shield your pond from falling leaves with a screen.
Ponds do not require very much water, and therefore it is advisable to place a reservoir in the yard in such a way that the plants are not far away and it will be possible to water the plants with old water from the pond using a pump.
4. Fish for reservoirs and ponds. Veil-tails and oranda, comets, koi and veil koi. Veil-tails are less aggressive than koi and comets. If you prefer veil-tails, don't keep them with comets and koi. You can keep comets and koi together, however many aquarists refuse to do this because of the value of their koi compared to comets.
5. How to change the water in reservoirs (ponds)? Change about 20% of the water twice a week. Remove old water from your pond and replace it with fresh water. You will most likely not need to add conditioner to the water if you change 20% or less. However, changing more than 20% of the water can be risky, even with the addition of an air conditioner.
How do you know how much is 20% of the volume of your reservoir? For example, if the reservoir is vertical (or almost vertical), therefore, 20% of the water will equal 20% of the depth of the reservoir. Measure the depth of the pond, for example 32 cm. So 20% of 32 cm is 0.20 x 32 cm = 6.5 cm. Thus, 6.5 cm of water should be drained from the pond twice a week.
If your pond is installed below ground level, then you will need a pump to pump out excess water. The funnel at the pump must be equipped with a special screen so that no fish is sucked into it. After you have changed 20% of the water, fill the pond with running water.
6. How to clean reservoirs. To do this, you need to purchase a 20 cm landing net with a handle so long that you can reach any part of your reservoir. Use a net to remove debris and leaves from the surface of the pond and from the bottom.
Part of the natural cycle in your pond will dissolve organic waste in the water, which you will later get rid of when you change the water. Thus, water changes are one of the most important steps in pond cleaning. Change 20% of the water in the pond twice a week.

7. How to feed the fish in the pond? Feed special floating foods that are suitable for pond fish. Sinking feed can be problematic. Start feeding 3 small pinches of food as soon as the fish have eaten everything - you can add some more.
Continue to feed the food in small increments and watch the fish feed. Avoid food residues in the water, if the food has not been eaten within 10 minutes, it must be removed with a net.
If you have any problems with the pond, then do not react too quickly and do not rush to change everything. This is a surefire way to turn a small problem into a big one. So even if the fish does not look very good, or behaves strangely, or even a couple died, it is not an option to ditch the entire reservoir. Just start changing 20% of the water every day. You can also add aquarium salt, or special preparations.
