Fishes and aquatic creatures thrive in rivers, oceans and ponds, where they have ample open area and water to move around. However, in smaller spaces, like aquariums and fish tanks, fishes need more attention. Fishes produce ammonia through waste and while breathing, which can pollute the water in the tank. Ammonia and nitrites must be removed from water, for which you need a fish tank filter. A fish tank filter is designed to keep the tank clean, so that fishes can thrive. Fish-friendly bacteria have a big role to play in this. We understand that it can confusing to choose between fish tank filters can be confusing, which is why we have discussed the basic aspects below.
What kind of filtration is the best?
There’s no single answer to that, but ideally, the aquarium water should be clean at all times, for which all three kinds of filtration – biological, chemical, and mechanical – are important. Biological filtration is the most important of the lot, because it ensures that good bacteria has surface to grow in form of gravel and sand at the simplest form, which helps in maintaining oxygen, as well. Mechanical filtration is what most filters do i.e. removing particulate matter from the tank, such as debris, plant waste and fish waste. Most of the fish tank filters offer a mix of biological and mechanical filtration and ensure that the water aptly oxygenized without ammonia and nitrites. Chemical filtration is often optional, but when needed, most filters use activated charcoal, which remove the extra toxins. With regards to chemical filtration, care must be taken because overdoing that can be damaging to the fishes.
Selecting a fish tank filter
First and foremost, you need to understand the kind of fishes and setup you are going to use for the fish tank. The setup for a saltwater tank is different than that of a freshwater tank. The size of the tank also determines the kind of fish tank filter you should consider. If you have a compact tank of 20-gallons or less, one of the compact filters should be more than enough. Secondly, consider a self-priming filter if possible, and don’t forget to check the flow rate of the filter. If you have a big tank, you need a fish tank filter with high flow rate.
Reviews, brands and more
There are some great websites out there that review different fish tank filters from time to time with a check on the pros and cons, and we recommend that you follow these portals for comparing the choices better. The brand always makes a big difference, so find a brand that can be relied on. There are also different types of fish tank filters out there, such as canister filters and sponge filters, and each of these offer different kinds of filtration that you may want to compare.
