My machines ENGLISH now.
Hello, I have a good one idea for tinkers, how one can save energy/money if luminescent material builds THRUSH one himself an Aquariumheizung from one. It gets hot and it can that Aquariumwasser warm. CAUTION! WHO CAN DO IT ONLY. I show photos in my home page.

I have already put this filter bill of exchange machine together for myself from Plexiplatten in 1985. It hangs from inside about the Aquariumrand. The filter material is a fine filter material audited by me physiologically.
The suspended matter taken by the filter, get daily, depending on dirt amount repeatedly out the filter circulation transports, this guarantees for duration the optimalsten Wasserdurchlass and the best suction power to get remote particles also further to the one sucking area.
Here do not become the taken substances by the constant water friction zerschlissen and harder substances do not remain in the water cycle for months meanwhile they give levy cloths to the water.
Bacteria do not take waste to pieces in the filter substance here either!
Microorganisms treat the pollutants already solved areas water touched on everyone but these himself situated and needing oxygen. This filter type which is different from all aquarium filters offered worldwide creates very considerably more waste the water out ALTHOUGH IT DOES NOT TAKE ANY MORE.
Its loft area is very small and therefore it gets still thick very fast AND THEREFORE THE SIGNALING TRANSMITTER PROVIDES regularly the further transport and therefore the best one let through AND THEREFORE ALSO, which gets less worn out.
To this filter can more advantageously differently strong pumps are attached, flat therefore, because it escapes from its dirt do way.
