What are aquarium water conditioners?

Aquarium water conditioners are treatments that remove harmful substances like chlorine, chloramine, and heavy metals from tap water, making it safe for fish and other aquatic life.

Is a water conditioner necessary for an aquarium?

Yes. Unless you are using pre-conditioned water, aquarium water conditioners are essential for neutralizing harmful chemicals in tap water. Without them, fish can be exposed to toxins that may cause stress or illness.

What happens if you forget to put a water conditioner in your fish tank?

Without water conditioner, chlorine and chloramine in tap water can irritate fish gills, damage their protective slime coat, and even be fatal in high concentrations. It's important to treat water before adding it to the tank.

How long can you let the aquarium water conditioner sit before adding fish?

Most water conditioners work instantly, allowing fish to be added right away. However, some formulas may require a few minutes to fully neutralize harmful chemicals. Always follow the product's instructions for best results.
