P10 used on Dennerle nano cube 30l

Fluval - P-Series Aquarium Heater - P10

I strongly disagree with the 1l -> 1w rule. If you go for the 2l -> 1w rule, this works great and cannot overheat your tank. (read more)

Heizt unkontrolliert das Becken auf

Wird in einem 55L Scapers Tank verwendet. Zimmertemperatur liegt bei 22°C und hab ne relativ "normale" Beleuchtung.

Der Aquarienheizer heizt leider unkontrolliert das Wasser auf, fernab von den angegebenen 24-26°C.

Habe am nächsten Morgen mein Becken mit gemütlichen 32°C auffinden dürfen (absoluter Supergau, brauche glaube ich nicht viel dazu sagen).

Habe anschließend den Heizer nochmal separat in einem Eimer mit ca 35°C warmen Wasser getestet (via Aquarienthermometer gemessen) und siehe da -- selber Effekt. Der Heizer hat unermüdlich weiter das Wasser aufgeheizt.

Kann leider zu dem Produkt nach der Erfahrung nicht raten.
