I still do believe that tunze is a better product. There is no noise, no parts to replace once you purchase a pump, it lasts forever with proper maintenance; The magnet is much better quality (if you own a tank with thicker glass), and the Tunze is much more powerful than the VorTech in my opinion (Tunze 6100 with controller versus MP40).
I was running 4 large tunzes in the tank and it was taking away from the Elos look so decided to go back to VorTechs. It's all about the presentation.
