In almost any aquarium a film of including microorganisms, dust, oils & food fats forms over time – the mould film. With the EHEIM skim 350 surface skimmer, you can efficiently eliminate this mould film & have a glass clear water surface & high oxygenation. The EHEIM skim 350, although designed for constant use is also suitable for short term use. If using alternately in several aquariums, please make sure that algae spores or diseases are not transmitted from one to the other. The bacteria & dirt particles which are sucked in are collected in the filter sponge. This should be simply taken out & thoroughly cleaned after each use. Eheim skim 350 at a glance: Removes surface films & microorganisms from the water surface Promotes proper gas exchange For both long term & temporary usage Quick installation
- easy to fix to the pane via suction cups Only 5 Watt power consumption

Biological filtration is based on the natural breakdown of pollutants carried out by aerobic bacteria, which can convert proteins & their by-products into less harmful substances. To maximise this process quickly & effectively, a highly porous filter medium is required to give the bacterial cultures the greatest surface area possible within the space available. Eheim Substrat provides a huge surface area of 450 m² per litre, offering optimal conditions for micro-organisms to flourish & delivering fast, effective filtration for salt & freshwater aquaria. Eheim Substrat at a glance: Standard bio-filter medium Highly porous material made from sintered glass Excellent conditions for bacteria cultures Reusable (rinse carefully to clean) Suitable for fresh & saltwater Tip: Never clean or change all the filter media together in one operation (and never clean too rigorously). The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be retarded. The filter baskets in the external filters & filter modules in the internal filters aquaball an biopower are ideal for partial cleaning. ...

SUBSTRATpro consists of pearl-shaped sintered glass. The spherical shape gives a high bulk density. Thus the whole of the volume in the filter (filter baskets or modules) can be utilised. Also the optimum surface of the beads provides intensive colonisation of the important purification bacteria. Due to the high number of bacteria, peak nitrite loads are more easily reduced & the maintenance intervals of the filter material are longer. EHEIM SUBSTRATpro is suitable for fresh & saltwater, is washable & can be reused. Eheim Substrat pro at a glance: Optimised bio-filter medium made from sintered glass High bulk density due to spherical shape (beads) Very dense colonisation of bacteria Longer intervals between cleaning Better reduction of nitrite loads Reusable (rinse carefully to clean) Suitable for fresh & saltwater Tip: Never clean or change all the filter media together in one operation (and never clean too rigorously). The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be retarded. The filter baskets in the external filters & filter modules in the internal filters Aquaball & Biopower are ideal for partial cleaning. ...

Eheim rotary pumps reliably perform all the standard functions of circulating extracting & transporting water. They can be installed in or out of the water & with flow capacities ranging from 270 to 2280l/h there´s a model to meet every aquatic need. Variable mounting & an integrated pre-filter & inflow hose attachment mean these products can be used for a whole range of functions (no ceramic storage!). Some suitable applications as extra circulation pumps; in conjunction with passive filter systems; for draining or replenishing tanks; or for hundreds of other uses around the home & workshop. No ceramic storage. Special Note This device is designed for use in Germany & thus will include a power adapter for use in the UK. What´s this? ...

Specially structured materials provide outstanding purification. Water permeates them evenly & coarse particle residues as well as even the finest particle residues are trapped mechanically Fine filter wadding made from special filter web is the last layer in the filter & traps the smallest left over particles. The pad must be changed each time the filter is cleaned ...
