Surface skimmer for ponds and pools  Simple and effective.  Size: 160 x 280 mm  Material: PVC, Styropor  reduction for 110 mm pipe Tank connectors for pond liner These tank connectors are made for a durable and safe connection between tanks and pond liners. The flange and sleeve are welded to guarantee high strength. We recommend commercially available silicone for waterproofing.     Pipe diameter: 40; 50; 63; 75; 90; 110; 125; 140; 160; 200; 250; 315; 400 mm  Material: PVC, grey  Screws: tapping screws DIN 7981; 4,2 x 19 bzw. 4,2 x 22  V2A Container for sensors The measuring chamber is made for four sensors. It can be introduced into the water circuit with a simple waterproof mounting. An optimum flow-through ensures accurate measurements and supports the self-cleaning effect of the sensors. This has a positive effect on the life of the sensors and reduces the need for maintenance.  Diameter: 110 mm Inlet / outlet : 20 mm Sensor diameter : 12 mm Flow-through reactor - versatile and space-saving Our flow-through reactor is compact and can be easily integrated into almost any system. It uses charcoal to filter out heavy metals or prevent ozone from reaching the tank water. Filled with carbonates, it neutralizes acids and stabilizes the pH. If you use a sulfur-nitrate filter for a seawater aquarium, the flow-through filter can be filled with hydrogen carbonate to neutralize the acids and promote the growth of coral and shells. Dimensions: Tube:		 110 mm Length:	680 mm & 1180 mm Connections: Inlet:       	1 x 50 mm  Outlet:      	1 x 50 mm   max. flow through:	 Pumping: 			depending on the filling Other: Material:			Plexiglass tube, PVC Pressure resistance:	pressureless operation  Weight:			~ 1,3 kg Trickling for wet and floating filters Trickling filter materials enlarge the surface area of biofilters to support the settlement area for bacteria and thus increase efficiency in the decomposition of organic compounds. We make our trickling filter material out of the leftovers from tank production. This means they are made of high-quality HDPE or PVC and are a first-class recycled product! Their special shape creates an enormous surface area of ​​about 790 m2/m3. Thanks to an innovative manufacturing process, we can produce trickling filter material with densities between 0.96 and 1.2. So we can offer trickling filters with optimum swimming properties for almost every application.
Breeding and rearing tubs for Artemia Artemia (brine shrimp) is a popular live food for marine and freshwater fish larvae. Because of its high nutritional value, Artemia is an essential part of today's fish farming. Our Artemia tubes are perfect for a quick and easy production of living food. The breeding tube has a spherical bottom to ensure optimal aeration and thereby increase the hatching rate. It is equipped with an overflow to the breeding tube. The breeding tube has a drain cock for feeding and a connection for the aeration system. Both tubes have a diameter of 160 mm and a volume of approximately 8 liters. They can be ordered as single modules or in combination with wall brackets or stands. The various sizes can be easily adapted to your needs.
Aretmia breeding station Artemia - fresh food for the fish (photo: J. Kahle) Large and robust - our airlift pumps Lift pumps are intended to move large volumes of water with little energy input. A compressor blows small air bubbles at the bottom of the discharge pipe. This causes an upward movement of the surrounding water into the tube. The advantages are: no electrical lines and pumps in the water, an easier maintenance and lower costs for energy! We construct your personal airlift pump. Just tell us what you need.

Typ 250 Typ 160 Ozone - to play it safe Ozone is used to disinfect the water and to reduce the load of germs and viruses in the fish tanks. In addition ozone breaks down stable chemical substances like humic substances, nitrite etc. It is also demonstrated that ozone decomposes a large part of the so-called off-flavor substances. Therefore ozone is the "all-rounder" in filter technology. But in the case of improper handling of ozone, its strong oxidizing effects can be dangerous for animals and humans. However, the risk for the animals can be reduced by a downstream charcoal reactor, for example our flow-through reactor. We sell our two ozone reactor models only to professionals. Offers Navigation
