تترا is the world's most recognizable brand in the aquatics industry, dedicated to helping hobbyists create thriving underwater ecosystems. Founded in Germany in 1951, Tetra pioneered flake fish food and has since expanded to offer a comprehensive portfolio of aquarium products. The brand's lineup includes advanced filtration systems, submersible heaters, water conditioners, and air pumps designed for both freshwater and saltwater setups.

Now a subsidiary of Spectrum Brands, Tetra continues to innovate with products like the Whisper® filter series and TetraFauna® for reptile care. Whether you are a beginner setting up your first tabletop tank or an experienced aquarist managing a large habitat, Tetra provides the reliability and expertise needed to maintain healthy fish and clear water.

• Why is my Tetra heater not turning on?

  Ensure the heater is fully submerged and plugged into a working outlet. Tetra HT heaters have an indicator light (red for heating, green for temperature reached). If the water is effectively at the preset temperature (usually 78°F), the heater will not activate.

• How do I quiet a noisy Tetra Whisper filter?

  Noise is often caused by a low water level allowing the impeller to rattle or draw air. Ensure your tank water level is near the top. Also, dismantle the impeller assembly to clean out any debris or sand that may be obstructing rotation.

• Where can I find the expiration date on Tetra fish food?

  The expiration date is typically stamped on the bottom of the can or canister. It is recommended to use the food within the dating period to ensure nutritional value for your fish.

• My Tetra air pump is running but no air is coming out. What should I do?

  Check for kinks in the airline tubing or a clogged air stone. Over time, air stones can become blocked by debris or algae. If the pump diaphragm is worn, repair kits are available for many Tetra Whisper models.
