Water supply for water cooling through a bypass in the existing water circuit of the filter system.

Average rating of 4.8 out of 5 stars
Delivery time, approx. 1-3 Working days
You can feed the water cooling system either through a bypass in your filter system's water circulation circuit or by means of a separate pump.
Illustration of the connection by bypass

- 180° silicone bends for connecting the feed and return sides.
Alternatively, several LED bars may be connected together. - Cooling and warm water connections; hoses can be cut to length as required.
- Cooling water feed by bypass. Select an adapter (T-connector) that matches the existing hose system. Use the hose line that feeds the filtered water.
Our recommendation: Alternatively, the cooling water can be supplied directly from the aquarium with a separate mini pump. This is usually safer and more reliable, as it is independent of the filter performance. See accessories: Mini pump

Ein bißchen DIY und es klappt prächtig
Das funktioniert. Aus der einen Richtung kommt das Kühlwasser und wird gesplittet. Nach anfänglichen Versuchen mit einer Zuleitung für 2 Röhren (= 4 Kühlkanälchen) - geht schief, weil der Widerstand zu groß ist. Dann nochmal gesplittet auf eine Zuleitung pro Röhre, das war's auch noch nicht. Jetzt habe ich 3 von den Y-Verteilern verbunden. Einmal die Ableitung nach links und einmal nach rechts. Dann nochmals pro Seite (=Kühlkanälchen) einen Y-Verteiler. Somit hat jede Röhre eine Zuleitung gesplittet auf 2 Kanäle und am anderen Ende den Abfluß. Das funktioniert prächtig, das Lampengehäuse bleibt kalt. Als Pumpe für die Zuleitungen habe ich mir einen billigen China-Skimmer umgebaut. Der hat genug Leistung und einen Filter (Filterwatte), läuft mit 4 Watt und ist absolut geräuschlos.
