The Laifoo Aquarium Siphon Vacuum Cleaner Washer is another great aquarium water changer on our list, especially for small and medium-sized tanks. Most aquarium water changers are over 25 feet long and are priced accordingly. But what if you don’t need a 25 feet long cable?

If the distance between your aquarium and your tap is no longer than 5 to 7 feet, then the Laifoo Aquarium Siphon Vacuum Cleaner is a perfect option for you. It is made for people who do not need a 25 feet long chord but still end up paying for it. This fish tank water changer comes in two different sizes, which are 5 feet and 7 feet long.

A very common issue with most products is that they do not have any filter on them, which results in small fish getting sucked up while changing the water in fish tanks. Fish have to be removed during changing water, making the process tedious and lengthy to avoid this issue.

The Laifoo aquarium siphon vacuum cleaner solves this problem. It has a screen inside the gravel tube, which prevents smaller fish from getting sucked into the tube. It also has a siphon ball that automatically directs water into the tube after a few pinches. This makes the process of creating the initial vacuum effortless.

Using it to draw the water in the tank is very easy. It has a PVC pipe that goes in the tank, and the other end goes into a bucket. To start draining the tank, all you have to do is press the siphon ball, and water automatically starts flowing into the bucket.

Things To Consider While Choosing the Best Water Changer for Aquariums

– Tube Length of the Water Changer

Always make sure to check the length of the water changer. It should be long enough to connect your tank to a water source. Many people connect their devices directly from the tap in the kitchen or the garden.

Thus a longer tube changer would be ideal for them compared to a person who would be using a bucket as a water source for smaller aquariums.

Most brands offer 25 feet and 50 feet for medium-sized and larger fish tanks. Some brands also offer smaller sizes ranging from 5-20 feet, perfect if you have a tap near your aquarium.

Most smaller-sized water changers come with siphon ball technology that eliminates the use of long tubes for their water changers. But you will need to empty your tank’s water in a bucket, which might not be convenient for some people. This is why longer tubes are considered to be more beneficial in most cases.

– Warranty

Most medium or low-priced aquarium water changers are generally of poor quality and result in wear and tear with extra water pressure. This would be a waste of money for anyone, and hence a warranty coverage by the company is essential.

Offering a warranty projects trust and security and also indirectly changes the perception about product quality.

Only a high-quality product would be with a warranty as the company has much more at stake than the consumers in this case. Hence, this can be a significant differentiating factor for fish tank owners looking for premium quality aquarium changes and after-sales benefits.

– Gravel Cleaners/Siphon Water Changer

Choose a water changer that also acts as a cleaner. The debris on the gravel is created from many different substances, including feces, dirt, algae formation due to chemical reactions, etc. It is imperative to remove it to maintain a healthy environment for the fish inside the tank.

This requires regular cleaning and a strong vacuum suction pump with a filter that removes all the debris and prevents gravel or smaller fish from getting sucked into the tube. Some brands also offer different types of nozzle attachments that you can use according to your need. A gravel cleaner with a filter is essential to ensure efficient cleaning of the aquarium fish tank.

All the water changers that we have mentioned in our list have a suction strong enough to clean your aquarium as well.

– Ceramic Filter

A ceramic filter is one of the most significant components to look at when shortlisting a water changer for a fish tank. As mentioned above, the debris collected is highly poisonous for the fish if not removed. However, physically removing the debris is not enough.

The invisible toxins like ammonia, ammonia nitrate, etc., are still present in the water due to the debris formation. A ceramic filter can remove them and purify the water back to a healthy state. If you are using a water conditioner, then this might not be a significant deciding factor for you because water conditioners neutralize ammonia.

However, if you do not use a water conditioner, we highly recommend choosing a water changer with a ceramic filter.

– Universal Adapter

Make sure your water changer either supports or comes with a universal adapter. A universal adapter would enable the water changer to get connected to any external source without any hassle.

This may seem like a small factor but indeed is very important. Many people spend extra money on such adapters because their aquarium water changers cannot be connected to their water source. This unnecessary expense can be avoided by filtering brands that do not provide this component.

– Squeeze Siphon Adaptor

A pressure controller can be beneficial in adjusting your water changer for a fish tank. If the aquarium you are replacing the water with has small or young fishes, then a strong vacuum force can put them under stress or even cause them injury.

Choosing a water changer with an adjustable vacuum pressure valve can help you set the right suction force for your aquarium. Newer brands have this inbuilt in their systems as it makes the process highly efficient. They have a single valve that controls the vacuum pressure and also the direction of water flow.

Many brands do not offer this with the main aquarium water changer kit, and people have to purchase it additionally, which can be an added expense. Therefore, a wise decision would be to filter such brands and choose the ones that have this technology built-in.

Conclusion

Changing the water regularly in fish tanks is extremely important for the well-being of your fish. If the water is not changed frequently, it can cause many health issues for your fishes and severely affect their lifespan.

However, If you are a working professional and you do not have enough time to do it. In that case, the Water Changers mentioned above will help you quickly change your aquarium’s water without any hassle.

While all products mentioned above are great for home aquarium maintenance, the Python No Spill Clean and Fill Aquarium System is the best value for money. If you only want to go for the best option, we recommend you go for this one.

Not only does it have a 12 month warranty period, but it is also available in different sizes. As mentioned, it is a little expensive but the features provided will help you immensely.
