It is always a good idea to get the freshest water possible for your fish pond. However, not all tap waters are safe for fish ponds. If you are looking to fill up your pond with tap water, make sure that you find out if the water is treated or untreated first.
Here are some things you should know before filling your fish pond with untreated tap water:
- Untreated tap water may contain chemicals and bacteria which can be harmful to fish.
- Untreated tap light could cause algae blooms.
- Untreated heavy metals in the groundwater could contaminate the surface of your pond.
- The pH level of untreated tap water can affect how quickly chlorine breaks down.
- Heavy metals in untreated well-water can lead to health problems in your fish.

How can I dechlorinate tap water for a pond?
If you do not dechlorinate your tap water first, toxins like ammonia and nitrite may accumulate to dangerous levels in your pond killing your fish. You can buy a dechlorinating product at a pet shop.
How do I dechlorinate tap water when filling a pond?
To dechlorinate tap water when filling up your fish pond, add two heaping scoops of sodium thiosulfate for every 10 gallons of water. This will help remove most of the chlorine from the water.
How long will it take for tap water to be suitable for pond fish?
Let the treated tap water sit for 24 hours to let it clear before adding it to your pond. This will allow the water to settle and any sediment or harmful chemicals in the tap water to sink to the bottom of your pond.
Do I have to dechlorinate tap water when filling a pond?
If you are using untreated tap water for your fish pond, make sure that you do not add the water until at least 24 hours after the initial fill-up. Letting the treated tap water sit for this long will help eliminate the toxins that come with untreated water.
For an average size pond, you will need about 10 gallons of treated tap water for every gallon of fish pond capacity. Let the treated tap water sit for 24 hours before you release it into your fish pond so it can clear first.
Is it better to use rainwater or tap water for ponds?
Rainwater is a great alternative to tap water for ponds. It contains no chlorine and the pH level is neutral which means it will keep your pond’s alkalinity levels at optimal standards.
However, like untreated tap water, you should dechlorinate the rainwater before use. You can do this by letting the water sit in an open container for 24 hours. This will let the chlorine evaporate from the rainwater. Make sure that you only fill your pond once all of the chlorine has dissipated from the water.
If you do not want to dechlorinate the rainwater, you can only use the water for aquatic plants.
Fish will not be able to live in untreated tap water because it may contain chemicals and bacteria which can be harmful to them. Make sure you know what’s in the water before filling your fish pond with it so that your beloved pets stay healthy.
How do I know if my water is treated or untreated?
If you are concerned about dirty tap water, you should ask your local city hall for an analysis of their well-water treatment processes. The records they provide should include the levels of total dissolved solids found in the water, which can be used to decide if your tap water is safe for fish pond use.
Normal tap water contains dissolved minerals and other chemicals that can be harmful to koi, goldfish, and other pond fish.
Experienced koi hobbyists recommend using filtered or distilled water when filling a pond. Using either of these types of water ensures there are minimal contaminants in your new pond. Distilled and soft water also makes it easier to keep the pH levels in your pond balanced, which can protect your fish’s health.
Filtering the water through one of these processes will remove most chemicals and impurities from the water, making it safe for use in your fish pond.
How much water should I add to my pond?
Make sure you never add too much water at once when filling your fish pond. If you add too much, there may not be enough nitrifying bacteria in the tank initially. This can cause a variety of problems with your new fish pond including algae outbreaks and dangerous toxin levels due to nitrogen overloading.
Only add about two or three inches of water every three days until you reach your desired level and make sure to dechlorinate the water before adding it to your fish pond. This ensures that there is a healthy amount of bacteria in the new pond for the nitrogen cycle to properly process.
How do I know if my tap water is safe for a fish pond?
A nitrate test kit should be the first thing you use to determine if your tap water is safe for fish ponds. The test kit will indicate nitrate levels in parts per million (ppm).
Normal tap water contains between 20 and 40 ppm of nitrates, which are fine for koi or goldfish ponds. If your new pond has over 100 ppm of nitrates, use a reverse osmosis system to filter the water before adding it to your pond.
If your new fish pond has nitrate levels of less than 20 ppm, you can add the water directly from the tap without filtering it.
How do I know if the water is too cold for my fish?
It’s best to let the tap water warm up to room temperature before adding it to your pond so that you don’t shock its inhabitants. This means you’ll have to use a heater or another device to heat the tank that holds your tap water. You can use an aquarium heater to raise the temperature of the tap water for several hours.
However, if you use an aquarium heater and it’s not marked for outdoor use, make sure to place it inside a waterproof container. You can also let your tap water sit out overnight to allow the chlorine and contaminants time to evaporate before adding it to your fish pond.
Untreated tap water can be very high in nitrates and phosphates, which contribute to the growth of algae.
In some areas, tap water is not as safe as it should be because of chemicals that pollute groundwater. In those areas, the local department of public health will issue a boil order before you are allowed to use untreated tap water in your fish pond.
If you are concerned about the quality of your tap water, contact your local department of public health for more information.
When filling a new fish pond, never add too much water at once and dechlorinate before adding it to your koi or goldfish tank.
Be sure to remove as much chlorine as possible by letting the water sit out for at least 24 hours or adding a chemical treatment.
After you have let the tap water sit, perform a nitrate test to be sure it is safe before adding it to your pond.
If your tap water has low nitrates and phosphates, fill your fish pond directly from the faucet without filtering the water.
