Which to get Vortech pump MP20 or Tunze ?

[Oscar]

I added a Vortech20 about 6 weeks ago and removed my Koralia 1. It is only set at 50% power and I seem to be getting much better flow which is really noticable whne I stir up the detritis. The Vortech20 has only 50% of the power of the Vortech40 and is not wireless. But you could add the battery back up and flash upgrade to the 40 if you need more power or want to add a 2nd head that is synched.

The power cord and attachment on the outside of the glass are noticeable for the 1st week, now I pay them little attention.
