Technical Components
Submerged Pump House
BIOTOP offers a pump house with a completely new concept. The pump is installed in a flooded pump house. The pump does not “draw in” the water but flows into the pump house without pressure. A submersible pump on the floor of the pump house transports the water into the pool through pressure lines.
The advantages of the Submerged Pump House
- Submerged pumps make only minor noise.
- The pump is so quiet it can be installed underneath the wooden deck.
- All suction and pressure lines can be regulated independently.

Curved Sieve Skimmer

The curved sieve skimmer is a milestone in skimmer development. The water flows over a curved sieve with a mesh size of only 0.3 mm. The impurities are removed from the system before the nutrients they contain get back into the water.
The sieve is self-cleansing and the flow is regulated by a float gauge that allows the right amount of water to flow over the flap.
The advantages of the curved sieve skimmer
- Removes even the smallest impurities.
- The sieve is self-cleaning.
- Despite the high cleansing factor, the sieve does not clog up.
- Animal friendly, comes with built in frog ladder.
The Phosphorous Filter - PhosTec Ultra

PhosTec Ultra - the ultimate in eliminating phosphorus. Without the use of chemicals the Phostec Ultra very effectively eliminates the phosphorous that is dissolved in the circulating water by binding it in its special filter material.
The advantages of the Phostec Ultra:
- Biological cleansing without chemicals.
- Backwashing water can be used for irrigation
- Easy to operate
- Low maintenance.
- Filter material can be changed easily
The Bio Compact Filter
The Bio Compact Filter system is concealed under the deck. The water flows through the filter vertically from top to bottom, whereby it is biologically cleaned. Impurities and organic compounds are broken down by bacteria resulting in crystal clear water. Optionally the Bio Compact Filter can be replaced by a biological filter and can be planted as an open basin filter. (More space necessary)
The advantages of the Bio Compact Filter system:
- No animals or plants in the water.
- Only small space required.
- Very clean swimming zone.
- Works with little energy.
