The 8 Best Hang-On Back Aquarium Filters
Filters are necessary for aquariums because they assist to maintain the water quality clean and fresh, which keeps the occupants healthy. To function effectively, every aquarium needs have some sort of filtration, and the first step is to locate the correct type of filter for your aquarium.
Many hobbyists dislike the look of filters immediately within the tank, which is where the advantages of a hang-on rear filter come in. Hang-on rear filters allow external filtration by clipping onto the aquarium's rims.
The majority of hang-on back filters produce a large amount of water, which generates a cascade on the surface. This may function as an aeration system, saving you money on a separate system that would damage the natural appearance of an aquarium.
When comparing various hang-on back filters for your aquarium, keep the size and stocking rate in mind. Some fish, such as goldfish, are dirtier and need a stronger filter than bettas or tetras.
The aquarium’s size is also significant, since a filter that only processes tiny volumes of water at a time is only useful for small aquariums, but big aquariums demand a greater flow and input system.
The filter should be appropriate for the design of your aquaria; for example, some hang-on backs may be used with both a fishbowl and a normal tank, but others are only ideal for a rectangle tank.
The manufacturer will usually state what sort of aquarium and water volume the filter can tolerate in order for it to function properly.
Purchasing a Hang-On Back Filter
- Choose a filter that is appropriate for the kind and size of your aquarium. If the filter is not suitable for your aquarium, you risk damaging it.
- The filter should satisfy your budgetary criteria and not be expensive for what it offers.
- Check that the filter has all of the filtering features you need. There are both opulent and simple hang-on back filters to suit various purchasers.
- Before making a purchase, ask the producers as many questions as possible. This enables you to assess how communicative the makers are, as well as how the product functions outside of the instructions and information panel.
GPH is used to determine the power of a hang-on back filter for a certain sized filter. The products discussed above have a minimum flow rate of 75 GPH and a maximum flow rate of 600 GPH.
These models are appropriate for small and big aquariums. Small hang-on back filters are normally intended for tanks under 20 gallons, and bigger hang-on back filters are appropriate for tanks ranging from 30 to 100 gallons.
Some filters feature an aeration system that saves you money over purchasing it separately. Some filters use cartridges to change the media for chemical and biological filtration, which should be bought separately from the same supplier to confirm that the media is compatible with your kind of hang-on back filter.
The Flow Rate
Filters with adjustable flow rates allow you to manage the flow of water in your aquarium. Most include an adjustable slider or dial that allows you to modify the rate at which the water runs through the system.
The flow rate required is determined by the species of fish you maintain. A good general rule of thumb is that all of the water in your tank should pass through the filter three to four times each hour. To put this into perspective, a 30-gallon-per-hour flow rate will filter around 10 gallons of water.
Installing a Hang-on-Back Filter
Hang-on-back filtration systems are simple to install, operate, and maintain. You’ll only take around 5 minutes to put it up after you’ve determined where you want it to go on your tank.
- Insert your filter media. Baskets are used in certain systems to designate where each media should go.
- Install your filtration system. The majority of tanks include a cut-out designed expressly for a filter. If your tank lacks one, you get to choose the placement.
- Filter should be primed. This entails filling it with water. You may skip this step if your filter includes a self-priming option.
- Insert the filter.
Back filter systems do not need much upkeep. However, if you find that your aquarium is becoming unclean, it is time to clean your filter.
Unplug your system, dismantle it, and clean the tubes and pipes thoroughly. Before you replace the system, change or clean the filter material.
