Y-Sonic 10

The Y-Sonic 10 Antifouling device prevents the adhesion of algae and mussels in the range of max. 10m ship length. Already infested ship hulls are also freed from algae and mussels in the long term.

Antifouling Y-sonic-10 — Position of the click generator for a motorboat, sailing yacht up to 10m LWL

The installation can be done by yourself or by your shipyard.

Is an antifouling on the ship, yacht, boat necessary?

We always recommend the combination of Antifouling with our click system. Nevertheless, we have very good References without antifouling, only with our click system, where only the hull is kept free by high-precision clicks. The decisive factor is the concentration of nutrients in the water. But there are too experience where, e.g. with a high algae concentration or a high worse quality of the gelcoat, hard lacquer the click tones are not enough alone, just like the antifouling. The combination Antifouling with the click system always works better than any system single.

Annual antifouling paints are no longer necessary, the ship’s hull glides better through the water thanks to the lower resistance. The biofilm still remains light but without algae or mussels. The yacht, boat, The hull of the ship is thus protected against algae infestation.

Due to the very low energy consumption of effectively 15 watts is the operation with battery-backed solar collectors possible. For the control the Solar Charger is in charge.

The Y-Sonic 10 has a preventive and curative effect on boats/vessels with fiberglas GRP, plastic, carbon, steel and aluminium hulls. The Y-Sonic 20 is for ships, yachts and motorboats over 10m length and up to 20m length.

G-Sonic 50 S

The natural G-Sonic 50 S algae control device is specially designed for large swimming ponds, natural pools, swimming biotopes, small lakes, fish ponds and water reservoirs due to its effective click sound range of up to max. 50 metres. Only 24 Volt signals are sent to the click generator, in compliance with the swimming pond standard VDE 702-100.

Click Generator Mounting — Click generator mounting clamp

The G-Sonic 50 S algae killer is absolutely maintenance-free and effectively prevents algae growth, thus ensuring clear water. Already existing floating algae die within a few days, green algae within 3 to 4 weeks, thread algae after approx. 7 weeks.

The G-Sonic 50 S algae remover also causes the biofilm (algae mucus layer) on the walls to be broken down by up to 2/3 and thus effectively prevents pathogens (pathogens) from multiplying.

When swimming, at most an interval-like clicking sound can be heard, as the human ear can hear through the skin.

With a short-time timer you can simply turn it off while swimming. Due to the very low energy consumption of max. 40 watts, operation with battery-buffered solar collectors is possible.

Sludge Bag

The fine filter sludge bag is for water recirculation and filters particles as small as 100 microns. The particles accumulated in the filter bag swell until it is completely filled. The purified water continuously swells out of the filter bag and flows back into the pond. The dimensions are fully extended approx. 160cm x 50cm.

Fine filter bags allow pond vacuuming without the need for a water loss. With this useful solution you can use pond water and return it to the pond after cleaning. The The fine filter bag is attached to the drain hose of the pond vacuum cleaner as usual. connected. With the supplied fixation strap you can fix the the drain hose in place.

For the fine filtration the fine filter bag is very suitable to return the valuable water. The danger of nutrient-rich refill water is averted by the water recirculation, so that no new nutrients (phosphates, nitrates, etc.) are filled into the pond, otherwise algae growth takes place again.

Included in delivery:

Fine filter bag approx. 160cm x 50cm
Hose anchor for 32mm, 38mm, 40mm, 50mm hoses
Velcro tape for fastening
Detailed instructions

First a pond basic cleaning is recommendable, since otherwise the bag can clog too fast. The fine filter bag is suitable for water filtration in order to return the valuable water.

If there is slight soiling, the fine filter bag can also be used directly.

After a quick basic cleaning and the discharge of dirty water, work should begin with the fine filter bag. In this way, the water throughput remains high. As a rule, permeability decreases during pond suction. In return, the filter fineness increases. This means that the water that is fed back into the pond has a certain turbidity. This turbidity disappears after 1-2 days and settles as fine precipitation in the pond.

Note: It still makes sense to first create a and the heavily soiled water is to be cleaned and the to be derived. In the aftermath, the fine filter bag can then be used to the water loss remains the same with this procedure. low overall, with only slight pond contamination the Fine filter bag can also be used directly.

Pre-Separator Tank

The pre-separator suitable for the algae-free pond sludge vacuum cleaner 8m3 separates stones, heavy leaves, newts, fish and frogs during pond cleaning. Depending on the pond bottom, you select the appropriate nozzles or brushes for extracting the sediments and are inter-coupled to the sludge suction unit on the suction side.

Pre-separator with connecting hose Ã38mm / 1 x C-coupling and filter mat — Pre-separator with connecting hose Ø38mm / 1 x C-coupling and filter mat

How does a pre-separator work?

The pre-separator collects this material, so it does not pass through the pond vacuum cleaner. The animals and possibly also stones can be removed again and returned to the pond. The separation works by gravity which means that suspended particles dissolved in the water are completely passed through while heavier particles remain in the pre-separator buoy.

The pre-separator is supplied with a sponge plate, which can optionally be used in some suction applications. This can be very helpful e.g. in autumn with freshly fallen leaves around the water then coarsely filtered back into the pond. In principle, however, the pre-separator is not suitable for filtering and is used without the sponge insert. If you really want to return the cleaned pond water to the pond, you need a separate filtering instrument.
