External Fish Tank Filters are quite popular with aquarists, regardless of the size of their aquariums. However, for larger aquariums, they fit a little more. Of course, there are small outsiders for aquariums of 10-20 liters, but the presence of such models is primarily due to the unique design.
The main feature of an external filter for an aquarium is that it is installed outside the aquarium: it draws water from the aquarium into one tube and throws the filtered water back through the other.
Inside the aquarium there is a small motor that controls the magnetic blade – it is this which makes the water move through the tubes.
There are filters of various capacities and, accordingly, performance. We recommend installing external filters in aquariums with a capacity of 200 liters or more. In general, for such volumes it is possible to choose an internal filter, but here the question is in the desire and availability of free time to take care of it. Large aquariums are usually purchased with bedside tables of the appropriate size, and in these pedestals a special place and shelves are provided for installing the necessary aquarium equipment.
Consider installing an external ASTRO 2210 Fish Tank Filter
It is intended for use in aquariums up to 400 liters and with fresh water. It is produced by ASTRO, a Chinese company with considerable experience in the development of similar products for aquariums. The main distinctive feature of the external filter ASTRO 2210 is its noiseless operation, as well as high performance. The power of the filter is only 13W, which is quite economical.
Preparation and installation of the external filter step by step
So, the external filter is purchased, it remains to install it and run it. To do this, you will need the following additional elements: a rag, or better two – in case of unforeseen water leaks or simply inaccuracy; a flashlight – in a cabinet, as a rule, it is dark or poorly visible; Stand made of soft material (if necessary).
Let’s start installing the filter:
- We unpack the filter, take out all the contents and study what’s what: as a rule, there will be the filter itself, two hoses, several plastic taps for water, internal sponges for the filter, filling (ceramic elements). We assemble the filter itself – it is possible that the alternate arrangement of the internal elements of the filter is drawn on the box. Until we connect the hoses to the filter. At the same time, the taps that are located on the filter cover must be closed (i.e., turn them perpendicular to the hose)!
- Now you need to prepare the external elements of the filter – in the aquarium. It is necessary to attach two plastic elements – one for water intake, the other for release. The first element is a long tube with a rounding – the long part is lowered from the side of the aquarium. The second element in the form of a short curved tube – water outlet – is attached to the other end of the aquarium. In parallel with the installation of elements, estimate the length of the hoses and the location of the external filter under the tank in the cabinet, so that later you don’t have to move anything.
- Here we come to the launch. Now we need to organize the filling of the filter with aquarium water using a drift. We connect the hose, which will take water from the aquarium (do not confuse – the filter says IN) to the filter using a special hose clamp with a thread – it is located on the filter cover (the skimmer must be closed). Open the inlet tap and the water begins to fill the filter by gravity. Closely monitor the level (so that water does not flow from the second hole of the filter) and as soon as the filter is filled, shut off the inlet hose. Next, we connect the exhaust hose, and we are almost ready to launch.
- We still have a second hose – for the release of water. This hose must also be filled with water (so that the air there does not interfere with the operation of the filter). This hose must be connected to the filter and cut off. Now pour water into the free end of the hose, filling the hose, and only after that it can be connected to a plastic outlet in the aquarium.
- Now we open both cranks on the filter (up to this point they should both be blocked) and only after that turn on the filter in the socket. The process has begun. And if the installation of the external filter is correct, then you will hear the filter grumbled and the water will start its movement :).
In general, installing an external filter for an aquarium is not difficult if you prepare for it and do everything in stages.
The main problem that arises during the installation of the filter is that water may not suddenly flow as it should. This may occur due to the formation of an airlock in the filter tubes. The problem is solved by turning the filter off and on several times in a short period of time. If you do not manage to pierce the airlock, then it is necessary to empty the hoses and fill them again.
