Aquatis Science Shark 25

This multi-chamber filter makes it possible to meet the purification needs varying from a very fishy pond of 10 m3 to a small swimming pool of 25 m3 (more if additional to a lagoon). Thanks to the mechanical pre-filtration to 0.3 mm of the Shark Sieve 300, a passage through eight brushes, an area of Biozeopond and an optimized decantation, the water is already rid of the majority of its impurities before crossing the Biocerapond. The surprising capacity for bacterial colonization (1450 to 3000 m2 / m3!) Of Biocerapond can thus be expressed for results that will not cease to surprise.

The addition of a UV sterilizer (AS UV S10 or 15) and a Hi Blow HP 20 Hi air pump (or more important if several ventilation points) are recommended.

Comes complete with Shark Sieve 300, covers, substrates, fittings and valves.

How does filtration work? 

- A mechanical prefilter, the Shark Sieve, uncompromising with dirt, retains any visible waste (0.3 mm and more) thanks to a self-cleaning grid of 300 µ (1). This preliminary purification provides a second essential treatment to the water: the runoff leads to a phenomenon of super oxygenation essential to the bacteria in the filtration, which thus find their performance increased tenfold.

- After a second mechanical purification by brushes (2), then a passage on Biozeopond (3), the water passes through the Shark filter chambers which are filled with Biocerapond (4), a bacterial support with performances never equaled.

- The rooms are large and wide in order to favor decantation. The optimized flow allows natural biochemical exchanges carried out by the "good bacteria".

- The foot, unique, has been developed to collect decanted waste (6) which will be evacuated by the opening of a valve.

- An aeration device (5) is integrated (excluding the pump) in each model with more than two chambers in order to promote biochemical reactions (which consume a lot of oxygen) until the end of the journey.

The many advantages of the Shark:

Mechanical pre-filter 300 microns 

Easy Clean® notches to ensure proper positioning and facilitate easy brush cleaning.

Thanks to their superior quality, SHARK filters are self-supporting. They must therefore not be buried or supported by an external structure.

All the models are equipped with resistant covers (1 per chamber) in fiberglass provided for a long service life.

Manually made of 3 + 1 layer fiberglass: guaranteed resistance and proven over time. Gel coated on the inside (smoothed perfect to avoid adhesion of waste), top-coated on the outside.

The water path is optimized: low emptying, upflows, counter-current ventilation.

The other advantages are not to be overlooked:

- Incorporation of Biozeopond upstream of biological filtration (retention of nitro compounds) with creation of an anaerobic zone.

- Compact, thanks, among other things, to the use of the volume entirely reserved for filtration substrates.

- Water path studied and optimized thanks to several years of experience: double wall between the chambers ("Up Flow" to optimize filtration (circulation from bottom to top)), optimized decantation without loss of space (in the foot) , aeration against the current in the "Up Flow", ...

- Impossible overflow of Shark Sieve (overflow incorporated), removable ultra-fine self-cleaning grid, ...

- Except through the wall, no visible piercing (leakage impossible): the fixing accessories are machined in the thickness of the filter (screws, support bars, ...).

- Models 2 and more bedrooms: the first bedroom equipped with AS brushes, the 2nd and 3rd 100% from Biocerapond.

- Each settling chamber is equipped with a 50 mm outlet with a guillotine valve as standard.

- Notches for reinforcement of the bottom grids provided for loading with heavier substrates.

- Delivered ready to use, provided with all fittings, valves, substrates, covers, ...

Feature :

Inlet: 25 - 32 - 40 and 50 mm barbed fitting. PVC connection 2 '' possible but not supplied.

Models 60, 100 and 150 (3 chambers) are equipped with a counterflow ventilation in the upflow between chambers 2 and 3 (barbed fitting 16-18 mm).
