Our Comprehensive Buying Guide
There are various things you need to do to take good care of your fish and keep them healthy. Besides feeding them the right formulas, your responsibilities include cleaning the mess they leave behind. To make sure you clean and purify the aquarium properly, you will need a good tank filter.
Even if your budget is limited and you look for a cheap goldfish filter, there are some factors you need to keep in mind in order to make sure the product you add to your cart will do its job well.
Types of filters
The market offers all sorts of filter models that provide different features to meet different needs. You will find air-driven internal filters that are ideal for compact aquariums and a great variety of fish tanks. Even if such models are small, they are sturdy and well-built.
Then there are the undergravel filters that are placed at the bottom of the fish tank under the gravel. They usually provide biological filtration by moving the water through the gravel and allowing beneficial bacteria to break down the waste accumulated in the tank.
Last but not least is the so-called wet/dry filter tank which is ideal for saltwater aquariums in need of biological filtration. It gets its name from a feature that allows such filters to be exposed to both air and water.
Another important aspect to pay attention to when looking for a filter for your goldfish tank is the type of function it provides. A filter that provides biological filtration will eliminate the ammonia accumulated in the tank. The mechanical process of a tank filter will remove the debris, dust particles, and excess food from the tank.
You will also have to consider the chemical filtration if you are not sure about the safety of the water you use for your tank. Since it might contain hard metals and materials that might prove harmful to the fish, using such a filter will help you clean up this type of impurities.
Power and canister filters
There are many categories of filters available on the market. The most popular models include the ones we’ve mentioned as well as the power and canister filters. The reason why we think you might want to consider them is that such models work with many aquariums and provide all the three functions.
Power filters are easy to set up and offer extended lifespan as well as the possibility to replace the filter cartridges. Although canister filters require more effort to set up and maintain, they offer the mechanical, chemical, and biological functions, power, and flexibility.
Aquarium tank size
Once you’ve made up your mind about the type of filtration you want, you need to consider the size of your aquarium. Filters provide such information on their label. You should read it carefully in order to choose a model that will work perfectly with your tank.
Also, keep in mind the water flow-rate which is measured in gallons per hour. Look for a filter that is appropriate for your tank and that will fill it faster.
