Shower Filtration
The principle or Showers or trickle tower filtration is well documented, and showers and trickle towers are without doubt the most efficient conventional biological filters available today. Water is pumped up to the top of the chamber(s) where it is dispersed via a spray bar over a tray of media. The water percolates through the given media and then trickles down to the next tray of media where the process is repeated until the water returns by gravity into the main filter system or pond. The super efficiency relates to the fact that the media used is not submerged but simply kept wet by the constant flow or trickle of pond water over it. This enable the nitrifying bacteria to multiple far more quickly than with a conventional filter because the media is effectively saturated with oxygen since it is not submerged. This provides the nitrifying bacteria with an abundant oxygen supply so the biomass establishes more quickly, and is much larger and more efficient than with conventional biological filtration. Showers mature quickly and as well as removing Ammonia and Nitrite, they can remove Nitrate as well as the huge oxygen supply enables some of the Nitrate to be ultimately converted to Nitrogen gas. Any good biological media can be used in Showers and trickle towers but favourites are Japanese matting and polypropylene medias as both are very light weight medias and easy to keep clean. Below you will see a choice of the very best units on the market.

Tornado 3 Protein skimmer
The latest model of the Tornado protein skimmer now features a ball valve for flow control and special new bio-rings for even better mix of oxygen. Thanks to the ball valve it is much easier to adjust the correct water level. Through a 4mm air connection and supplied flowmeter an air pump continuously pumps 0,5l/m (30l/h) air into the filter. This pressure ensures that the foam is pushed out of the filter through the foam outlet tube. The protein skimmer is a combination of a biological, mechanical and chemical filter. The principle works as follows: the surface of an air bubble attracts substances dissolved in water. Due to the attraction of air bubbles, chemicals, dirt particles, dyes and algae are attracted to the foam produced. Air is mixed with water by means of an air pump. By forcing this mixture through the filter material (biorings) to a lower outlet, a very long contact time between water and air is created. This changes the surface tension of the water continuously and creates a firm foam. This foam is separated from the purified water by a perforated cone and discharged. Substances dissolved in the water such as phosphates, ammonia, Humic acids, dyes, proteins and a number of heavy metals are filtered out of the water and discharged by means of the foam.
Water inlet: 25mm, water outlet: 40mm, foam outlet: 25mm.
