An external filter is a must for large aquariums. When choosing a model, you need to take into account not only the quality of the filter and the volume of the aquarium, but also the convenience of its use. For most users, the main repulsive factor in the device is noise, so pay special attention to this.
Instructions
Step 1
Obviously, the external filter is installed outside the aquarium, so it is necessary to plan a place for it in advance. Users claim that external filters are much more convenient to use than internal ones, as they are always available for service. Before buying, first of all, you should find out how much power your future filter should have. It directly depends on the volume of the aquarium.
Step 2
If you are the owner of a small aquarium, then mainly pay attention to the quality and noise indicators, because the requirements for the filter power are low. Carefully study the manufacturer's recommendations, the volume of your aquarium should be slightly less than the recommended norms, otherwise the filter may not cope with its work. If your aquarium is quite large, then consider also its dense population. It happens that there are a lot of inhabitants, in this case it is worth purchasing a filter with a large power reserve.
Step 3
For small aquariums between 30 and 70 liters in volume, the external filter should have a capacity of 300 to 400 liters per hour. This should be enough, even if the artificial reservoir is densely populated. In this case, external filter models such as Aquael Filter MINI KANI 80, Aquarium Systems MILLENNIUM 1000 and Tetratec EX 400 are available.
Step 4
If we consider another group of aquariums, the volume of which is from 60 to 100 liters, the filter performance should be higher. On average for this group, it is 500 liters per hour. As for specific models, you can pay attention to the external filter Tetratec EX 600, the manufacturer's recommended volume of the aquarium is up to 120 liters.
Step 5
For larger aquariums, the range of external filters is very diverse. The bandwidth, of course, should be higher. For example, for a volume of 100 to 200 liters, on average, it is 700 l / h. This is the capacity of the EHEIM Professionel 2224 filter model and is designed for aquarium volumes up to 250 liters. External filters designed for huge volumes are generally available today. For example, the EHEIM Classic 2260 is capable of serving an aquarium of up to 1500 liters with a capacity of 1900 liters per hour. The range of external filters is really wide, so it won't be difficult to find the right model for you.
