Overview of external canister filters Tetratec EX 400-2400. In this article we will take a closer look at the external canister filters Tetratec EX 400-2400 and their device. As you have probably already guessed, this line of filters includes external canister filters for an aquarium produced by Tetra. Let’s see what the external canister filter Tetratec and the whole line of canister filters for the aquarium are and what surprises the creators of these biofilters have prepared for us.
So. Overview of external canister filters Tetratec EX 400-2400.
The line of external canister filters Tetratec EX includes canister filters for an aquarium of the same design, differing among themselves only with some details and different nominal power.
In particular, Tetratec EX low-end filters have a smaller canister volume (the younger the model in the Tetratec line, the smaller the filter canister volume). In addition, the older models of canister filters (Tetratec EX 1200-2400) have a larger section of hoses and nozzles, and hence a greater throughput of the entire Fish Tank Filter as a whole. In addition to the volume of the canister, Tetratec EX external Fish Tank Filters are also distinguished by the number and volume of baskets of various fillers placed in the filter canister, Uwwportal.ru notes. The younger the model of the Fish Tank Filter, the smaller the number of baskets can be placed in the canister. The older models of Tetratec canister filters (Tetratec EX 1200-2400) differ from the younger ones by the volume of the filler baskets themselves.
Below is a list of external canister filters for aquariums in the Tetratec EX external canister filter line:
External canister filter Tetratec EX 400 (This filter is recommended for aquariums with a volume of 10-80 liters).
External canister filter Tetratec EX 600 (This external filter is recommended for aquariums with a volume of 60-120 liters).
External canister filter Tetratec EX 700 (This external filter is recommended for aquariums with a volume of 100-250 liters).
External canister filter Tetratec EX 1200 (This external filter is recommended for aquariums with a volume of 200-500 liters).
External canister filter Tetratec EX 2400 (This external filter is recommended for aquariums of 400-1000 liters).
Now let’s move on to the main design features common to all external canister filters of the Tetratec EX line.
All canister filters of the Tetratec EX series consist of a canister with vertical loading and a removable lid detachable from the canister.
In the lid of the canister filter Tetratec EX there is one electric and one hand pump. Two nozzles for incoming and outgoing aquarium water flow, as well as a power supply cord, are connected to the lid of the Tetratec EX canister Fish Tank Filter. In addition, the Tetratec EX canister Fish Tank Filter cover is equipped with a retractable plastic handle located in the upper part of the canister filter cover and two special fastenings located on the sides of the cover, with which the cover is kept in an airtight, interlocking state, forming a single unit with the filter canister.
An electric pump, mounted in the lid of the Tetratek canister filter, serves directly to create a flow of water through the filter. It is noticed that it can make noise during operation, if there is some air left in the system, after the air has been removed, the filter works almost silently.
A manual pump is used to pressurize the primary pressure and fill the entire filter system with water before starting. The electric pump filter does not have enough power to create a primary pressure in the filter for the initial filling of its water.
The handle, located at the top of the canister filter cover, is retractable, plastic. It is possible to carry a filter filled with water, but it is still not recommended to make sharp movements, this pen is too fragile.
The external canister filter for the Tetratek aquarium has a standard fixed electrical cord (this is true for the entire Tetratec Fish Tank Filter line described in this article).
The nozzles located on the lid of the Tetratec canister filter have a bevel and rotate in a horizontal plane. Nozzles are attached to the hoses by means of special adapter valves (the valve can regulate the power of the water flowing through the Fish Tank Filter). Adapters are attached to the nozzles by a threaded connection and are also movable in the same plane, which, being assembled into a single structure, provides a very flexible and adjustable connection that allows you to avoid twisting and kinking of the hoses. All items are made of plastic.
The two mounts, located on the sides of the lid of the Tetratek canister filter, as well as the previous parts, are made of plastic. Fasteners have a special clamping mechanism-closer, providing a tight fit of the cover to the filter canister.
We now turn to the canister external filter.
The canister of the Tetratec filter has only one remarkable element – the second pair of fasteners that provide a tight connection between the canister and the filter cover in a single unit.
Tetratec EX canister filter basket fillers (bottom to top): ceramic rings for flow splitting and primary mechanical filtration; biochars for the settlement of beneficial bacteria and increase the efficiency of the biofiltration process; large pores for additional biofiltration and mechanical cleaning; synthetic winterizer for residual fine mechanical cleaning; permeable coal bag for additional water treatment (needs to be replaced periodically).
Hoses and other elements of canister filters Tetratec EX. Also Tetratec EX canister filters come with 2 transparent hoses, a composable flute, a telescopic water intake tube with a safety grille and plastic fasteners with suction cups for the flute and the water intake tube.
General impressions of Tetratec EX filters are very favorable. These filters work almost silently (especially if the flute is located below the water level in the aquarium), no leaks and other troubles have been recorded for more than three years of continuous operation.
Among the shortcomings can be noted the periodic silting of the hoses of the external Fish Tank Filter, the gradual slight loss of elasticity of the Tetratek hoses at the joints (which is not terrible and is completely compensated by a well thought-out mounting, but still there are hoses without Tetratek complete hoses for such a problem) There is also a certain weakness of the electric and manual pump, which manifests itself with a large drop in water level during the first start-up and filling the filter with water. However, in general, these disadvantages of Tetratec EX canister Fish Tank Filters are not so critical as to be a serious contraindication to their purchase.
