Filter spray nozzles that feeds at a small distance are arranged above the water surface, so that the water sprayed out of the nozzles when it hits the surface of the water in the aquarium Air entrains in more or less large bubbles »The aeration of the water, which is achieved in this way, is just inadequate. In addition, if poisoning of the water is to be avoided, the filter must be used for a short time Be replaced at intervals. But this is because most of the device is outside of the aquarium and only the suction line or the office guide line with the nozzle openings in or above the container are arranged, annoying

The invention is based on the object, in particular the deficiencies and difficulties mentioned above with the known cleaning and ventilation devices for the water in aquariums see below. The invention sees for this purpose in a device of the type mentioned for cleaning the water in aquariums and for enriching it with air, one of which is a water cycle a filter effecting pump includes, before that the pump and the Filters are arranged in the aquarium itself and the pump does water to be cleaned in a lying above the filter

-Tree promotes from which it is due to the difference in level between the water level in this tree and that one in the aquarium through the filter into a tree below, from which it flows through preferably horizontal openings in the aquarium. One special Effective equipment is obtained if one takes care that there is a tree in the tree following the filter Air cushion is maintained and the water leaving the filter in drops through the air cushion in the water below falls »

The pump and filter with the upstream and downstream rooms are expediently combined into one unit ο Here you can use a kind of compressed air lifter as a pump to convey the water, which consists of one at the bottom End is formed with access openings for the water and an air inlet sdüae provided upright drilling, that at its upper end with an outlet opening communicating with the tree above the filter is provided. Sas filter can in turn in a housing be inserted or hooked in, with its upper band a certain distance above the water surface in the The aquarium protrudes and is open at the top.

a tree in which the outlet opening remains above the filter the pump empties, while the bottom of the housing

lies at a certain distance from the lower edge of the filter and the housing side wall has outlet openings in this area for the water owns. In the tree and remaining between the lower edge of the filter and the bottom of the housing in the preferred embodiment of the device, one opens, preferably in the vicinity of the bottom of the housing "Another air line. Both air lines, i.e. the one to the pump and the one opening into the space below the filter, can be fed from a common compressed air source, in which case the amount of compressed air flow through each Line can be regulated separately.

In the drawing, a gate direction according to the invention, which can be conveniently accommodated in a corner of an aquarium, is shown with the parts essential for understanding the side wall of the aquarium is denoted by 11 * The bore of the feed pump 13 is on its bottom 12 with a base plate 14, which can be covered by sand. The pump tube 13 is provided at a certain distance above the base plate 14 with openings 15 for the entry of the water from the aquarium. In the vicinity of the base plate 14 is also through the bore wall 13

an air supply pipe 16 is guided, which is connected to a compressed air source via a hose line 17 The outlet opening of the tube 16 is covered by a block 18 made of porous material, which as a nozzle with a A large number of fine openings acts, from which the air exits into the pump tube 13 filled with water. That Water heavily enriched with air rises due to the reduced specific gravity in the pump tube 13 and flows through the outlet port 19 into a cylindrical housing 20, which is directly attached to the feed pump 1? adjoins

The housing 20, which is open at its upper end, so that the conveying air entering from the pump tube 13 via the outlet opening 19 with the water can escape, protrudes with its upper edge a certain distance above the liquid level in the aquarium and extends approximately to the height of the upper edge of the. aquarium, but could also extend about the pump tube nominal extended accordingly, and is higher laid the Aualauföffnung 19 according · in the sylindrisohe housing HO © is contains zyllndrlschor container 2f moved ei ^ plague "of Fe® filter material and ea his Hmim $ ® diwah Biehftiagse ^ ffeifeii 23

is sealed with respect to the housing 20. This! Filter container 21 can be suspended from the upper band of the container 20 by means of hooks 24. In the bottom of the filter container outlet openings 25 are provided for the filtered water « Per bottom of the filter housing is at a certain distance above the bottom of the housing 20, so that between Both a tree 26 remains in which the filtered water The side wall of the housing 20 is at a certain distance below the bottom of the filter housing e provided with openings 27 through which the water from the tree 26 enters the aquarium again. In the bottom of the Housing 20, finally, an air outlet pipe 28 is also arranged »whose mouth in turn with a block 29 is covered from porous material and via the hose line 30 with the Ijufteuführungsleitung 17 in connection stands ο

]) ae device works as follows. In the starting position, i.e. if no air is supplied via the hose line 17 and everything is at rest, the liquid level is fft in the fumpenrolir 13 and in the container 20 on the same Height like in an aquarium · When supplying compressed air above the pipe 16 and the Klota 18 rises the water in the Tube 13 a »and continuously sucks in new things through the openings 15

from the aquarium to · The heavily enriched with air Water flows through the outlet opening 19 into the tree 31 in the container 20 _9, which is above the filter 22, whereby a large part of the air permeating the water escapes into the open. The water then flows down from the space 51 through the filter and exits through the openings into the tree 26 in a purified state. In this tree 26, an air cushion is maintained via the hose line 30 and the air supply pipe 28 »that from the bottom of the filter» *

housing 21 extends to the level of the uppermost outlet opening 27 and optionally by lifting the Filter housing 21 can be enlarged. Because of this air cushion more fall out of the openings 25 or less large drops in the water below, whereby they entrain air bubbles in the finest distribution, which immediately afterwards ait the outflowing water from the openings 27 exit into the aquarium.

A particular advantage of the device described lies in »that it allows a strong enrichment of the filtered water with air and, since the suction parts of the Water is at the bottom of the container, ensures a constant circulation of the entire amount of water
