What Is An Aquarium Vacuum?
An aquarium vacuum is a very useful piece of equipment to own if you keep fish. Although they are small, fish can be messy and cleaning their tanks is not the easiest job in the world. A gravel vacuum helps you to keep their tank clean as it sucks up all the dirt, debris and waste your fish produce and leaves them with a sanitary environment. The vacuum usually consists of a plastic tube that sits in your tank and continuously drains water from it until you remove it.
Do I Need The Best Aquarium Vacuum?
If you own fish, the best aquarium vacuum is going to make your life a lot easier all around! First and foremost, a vacuum helps to keep the tank clean. Over time, fish waste, dirt, uneaten food and debris will begin to accumulate at the bottom of the aquarium with the substrate and trying to remove it can be tricky. Whether you use fish tank gravel or sand substrate, it doesn’t matter, they will both hold onto waste. A gravel vacuum helps to quickly get rid of all the unwanted waste and leaves your tank fresh. This can also help to lengthen the time between water changes.
Water changes are an essential part of fish keeping, but they can be a pain. Fortunately, an aquarium vacuum can also be used to help. The vacuum can be used to suck up the water and makes changing the water a lot quicker! Even better, you can change the water and clean your substrate at the bottom of the tank at the same time.
Types of Aquarium Vacuum
There are two main types of gravel vacuums — a siphon vacuum and an electric vacuum. Both have their benefits and drawbacks and it will be up to you to decide which one is going to be the best aquarium vacuum for your tank.
Siphon Gravel Vacuum
A siphon gravel vacuum is the most popular type of vacuum. Fairly cheap and available in a wide range of sizes, this vacuum is easy to use because gravity does all the work. However, because it sucks up water as well as the dirt, you’ll need to drain your tank every time you use it. This is the best vacuum if you want one that can be used during water changes.
Electric Gravel Vacuum
An electric gravel vacuum is more expensive than a siphon gravel vacuum. They don’t drain your tank and instead pumps the water through the vacuum, trapping any dirt, debris, waste and food in the filter. These can be much easier to use and are great for cleaning the bottom of the tank between water changes. However, they are usually used in conjunction with a siphon vacuum, as you will need to be changing your water regularly anyway.
Features To Consider When Buying The Best Aquarium Vacuum
There are a few things to consider when buying the best aquarium vacuum to ensure you get the right one for your tank and your fish and plants.
Tank Size
First and foremost, consider the size of your tank when purchasing a gravel vacuum. Some vacuums suction the water out very quickly and, if you have a small tank, this could pose a problem for your fish! A smaller vacuum works for a smaller aquarium.
Type Of Vacuum
As we have mentioned above, there are two main different types of vacuums — a siphon vacuum and an electric vacuum. A siphon vacuum is cheaper, but you will need to drain your tank every time you use it. An electric vacuum can be used for quick cleaning between water changes, but is generally more expensive.
Fish And Plants
Take into consideration the size of your fish and plants when purchasing a fish tank vacuum. You don’t want any accidents (ie. your vacuum sucking up your fish), so make sure you purchase one with a small enough nozzle. Fortunately, most gravel vacuums come with safety features built in to stop any accidents from happening.
