• A ground heating ensures thermal circulation of the almost natural soil substrate and thus promotes the transport of nutrients to the roots of the plants.
• Easy installation: Place the cord heating in curls on the window of the bottom of the aquarium, fix it with the suction cups
• The climb of heated water is followed by a colder water supply and thus ensures water circulation in the ground. The soil turns in addition into a natural filter for the aquarium.
• Large section of the heating cord for more efficiency, 24 V safety voltage against the dangers and high -quality power supply. Spring pliers allow a toolless assembly.
• Contents: ground heating for aquarium, electric transformer, heating cord with hot/cold conductors, fixing suction cups.

Circulation of water
in nature, aquatic plants grow better when they have sources of runoff rich in nutrients. Plants feed on it. Due to the low warming of the soil, the water rises and the cold water, full of nutrients and dissolved minerals, descends, creating a thermal flow which brings food directly to the roots.

Simple installation
Place the heated cord in regular curls (in the area where plants must be planted) on the cleaned bottom window. Set the heated cord using the split suction cups provided. Take out the 2 cold aquarium drivers and fix them to the power supply. The separation of a cold and hot driver is clearly visible to black lines on the cable.

Use without danger
to use it without danger in the aquarium, the heating cord is sheathed in silicone and works with a low -consumption voltage power supply 24 V. Install this block in a well -ventilated and protected location of splashes. Floor heating ensures slight warming of the floor substrate, but must be completed by a thermoplonger (JBL Protemp S) for hot water fish.
The power supply blocks heat up during operation, which is normal and purely technical.

Advice
those who do not like to use suction cups to fix the heating cord can fix it permanently with small drops of silicone and then remove the suction cups.
