How do I add water to my fish tank without killing fish?

Tap water contains chlorine to kill bugs and make it safe for us to drink. That chlorine can also kill beneficial bacteria in our filters and harm fish, so we must always add a liquid dechlorinator (also known as tap safe or water conditioner,) every time we introduce new tap water to a freshwater tank.

Adding water to your fish tank without harming your aquatic companions requires careful planning and consideration. Here’s a step-by-step guide to ensure the well-being of your fish during the water-changing process:

Preparation and Water Source: Before adding new water, ensure it’s free from chlorine, chloramine, and heavy metals. Use a water conditioner to treat tap water or consider using dechlorinated water. Match the temperature of the new water to the tank water to avoid temperature shock.

Gradual Addition: Slowly add the treated water to the tank. Using a clean container or hose, gently pour the new water onto your hand or a plate submerged in the tank. This prevents disturbing the substrate and minimizes stress for the fish.

Acclimation: If the water parameters of the new water are significantly different from the tank’s parameters, consider acclimating your fish. Float the fish in a bag or container filled with the new water for about 15-20 minutes. Gradually add small amounts of tank water to the bag to help the fish adjust to the new water chemistry.

How should I add new water to my fish tank?

Let cold water run from the tap for a few minutes to flush out any minerals or residue from the lines. Fill a clean bucket approximately two-thirds to three-fourths full with water. Slowly pour the water from the bucket onto the plate in the aquarium.

Adding new water to your fish tank is a crucial aspect of maintaining a healthy aquatic environment. To ensure the well-being of your fish and the stability of the tank, follow these steps:

Preparation: Prepare the new water by using a water conditioner to remove chlorine, chloramine, and heavy metals. Make sure the temperature of the new water closely matches that of the tank to avoid shocking the fish.

Slow and Gentle: To minimize stress and prevent disturbing the tank’s substrate, pour the treated water onto your hand or a plate placed in the tank. This disperses the flow and prevents direct impact on the fish.

Gradual Addition: Add the new water slowly. If you’re changing a significant portion of the water, do it over several hours to avoid abrupt changes in water parameters that could stress the fish.

Acclimation (if needed): If the new water’s parameters are different from the tank’s, consider acclimating your fish. Float the fish in a bag or container filled with the new water for about 15-20 minutes, gradually adding small amounts of tank water to the bag. This helps the fish adjust to the new water chemistry.
