Trickle Tower Filtration
The principle or trickle tower filtration is well documented, 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 of trickle tower filtration 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. Trickle towers mature quickly and as well as removing Ammonia and Nitrite, 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 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.
Standard Trickle Tower/Shower.
This super multi tier trickle tower is made from robust polypropylene, with a welded construction, and comes complete with a 2" spray bar assembly, lid and weir exit shute. As standard it is supplied in a three tier configuration, but more tiers can be added if required.
Dimensions 1 metre wide x 1 metre high (with three trays) and 25cm deep.
Supplied with perforated media trays to hold your chosen media. We recommend Japanese matting as it is so light and easy to clean when necessary and super efficient.
This represents fantastic value for money, being less than half the cost of some trickle towers of similar capacity.

Red Lable Aquaking Showers
The Red Labbel Aquaking range of trickle towers/Showers feature two 4 tray systems, one smaller unit, one larger unit. The smaller unit has a single spray bar whilst the larger has two. The units come complete with a 2" spray bar assembly, lid and weir exit shute. As standard they are supplied in a four tier configuration.
Dimensions: Smaller unit - 66.5cm wide x 94.2cm high and 32cm deep. Large unit: 100cm wide x 120cm high and 42cm deep.
Supplied with perforated media trays to hold your chosen media. We recommend Japanese matting as it is so light and easy to clean when necessary and super efficient. Other medias such as Crystal Bio ceramic media is also very good in this kind of bio-filter.

Clarity Protein Skimmers
Clarity protein skimmers were developed in Norway for both commercial fish farming operations and Koi ponds. They represent the very beat technology in protein skimming as they work on a somewhat different principle to conventional skimmers. It has always been more difficult to get efficient protein removal from fresh water applications since bubble sizes produced with fresh water are large in comparison to salt water applications and therefore skimmers tend to be less efficient in fresh water. Clarity has overcome this problem using patented design technology and these units work just as well with fresh water applications and are super efficient. So efficient are they in fact that they not only remove DOC (Dissolved Organic Carbon), proteins and fine solids from the water, but they also lower Nitrate and Phosphate levels substantially, something which normally requires very special filter equipment. However there is another huge difference between Clarity and other protein skimmers - they are not just protein skimmers, but complete biological filters in their own right. The CL3 contains 50 litres of HSA type polypropylene media - as much as a Nexus 220! In addition, because Clarity utilises this media in a Trickle tower configuration, it is biologically much more efficient than having the same amount of media in a conventional filter. So with Clarity installed, there is no need for further or additional biological filtration. Therefore a Clarity system can replace a conventional biological filter completely and will give excellent water quality. Clarity represents one of the most amazing breakthroughs in filter technology in recent years.

Treatment with Clarity™ gave approximately 40% reduction in total nitrogen, nitrite and nitrate in a 30,000L fish pond after just 9 days with recirculation every 5 hours. Please note that the water source contained approximately 67kg live fish which were being fed 0.8kg food daily throughout the test.
Clarity units need no forced air input or venturis to create the foam, unlike other protein skimmers. Apart from the fabulous efficiency, they only need low power pumps to run them so running costs are very low. The new Clarity models shown right now feature twin waste collection pots and the waste outlet can be on the right or left.
