Why Fish Tank Non Return Valve is Necessary

As an avid fish keeper, I have learned the hard way the importance of having a non return valve in my fish tank. At first, I thought it was just an unnecessary accessory and didn’t bother getting one. However, after a few incidents, I realized how crucial it is for the well-being of my fish and the overall maintenance of my tank.

Firstly, a non return valve prevents water from flowing back into the air pump or powerhead. This may not seem like a big deal at first, but trust me, it can be disastrous for your fish. If water gets into these devices, it can damage them and even cause electrical hazards. Not to mention, if the pump or powerhead stops working due to water damage, your tank’s filtration system will be compromised and can lead to poor water quality and sick fish.

Moreover, a non return valve also prevents air from flowing back into the water during power outages or when changing water in the tank. This may not seem like a significant issue, but when air enters the water, it creates bubbles that can disturb the oxygen levels and carbon dioxide balance in the tank. This can be harmful to your fish as they need a stable environment

My Buying Guide on Fish Tank Non Return Valve

As a fish tank enthusiast, I understand the importance of having all the necessary equipment to ensure the well-being of my aquatic pets. One essential item that every fish tank owner should have is a non return valve. This small device plays a crucial role in maintaining the proper functioning and safety of your aquarium. In this buying guide, I will share my knowledge and experience to help you choose the best non return valve for your fish tank.

What is a Fish Tank Non Return Valve?

A fish tank non return valve is a small plastic or metal device that allows water to flow in one direction only. It is typically installed on the air tubing that connects an air pump to an air stone or bubble wall inside the aquarium. The valve prevents water from backflowing into the air pump, which can cause damage and potentially harm your fish.

Why Do You Need a Fish Tank Non Return Valve?

Without a non return valve, there is always a risk of backflow or siphoning in your fish tank. This can happen if there is a power outage, or when you turn off your air pump for maintenance purposes. Backflow can also occur if you accidentally submerge your air pump in water while cleaning your tank. A non return valve acts as a safety measure to prevent any water from flowing back into your air pump and causing damage.

Factors to Consider When Buying a Fish Tank Non Return Valve

1. Material: Non return valves are usually made of plastic or metal. Plastic valves are more affordable but may not be as durable as their metal counterparts. Metal valves may be more expensive but can withstand higher pressures and last longer.

2. Size: The size of the valve depends on the diameter of your air tubing. Make sure to check the diameter before purchasing to ensure a proper fit.

3. Compatibility: Some non return valves are designed specifically for certain types of air pumps or air stones/bubble walls. Make sure to check compatibility before buying.

4. Ease of Installation: Look for valves that are easy to install and do not require any special tools or skills.

5. Brand Reputation: It is always advisable to buy from trusted brands with good customer reviews and ratings.

6. Price: Non return valves come at various price points, so make sure you choose one that fits your budget without compromising on quality.
