Tunze 9012 DC performance


New member
Hi !

I've been using the Tunze 9012 DC for cca 2 years, in the first 5-6 month i can run at 20-30 % , beacuse its overflowing, I always need to increase the skimmer performance. Now its run at 100% , and dont have a strong foam. (completely disassembled and cleaned)
Is something need replace? rotor or the motor?

the outside of the power cord which is in water is damaged in some places, can the inside corrode? i think it is not replaceable, it is cast in the engine?

And the another question, where its the max ?


Thanks for the help !
