    I recently had the privelege of going out in a glass bottomed boat in one of our marine reserves, called Goat Island. One thing I very much noticed was the water and wave action, kind of more noticeable from a boat than when diving and actually part of it.
    As we passed over areas with swaying types of growth, it was a relatively calm day, however the water would move one way, and everything would be pushed over that way for maybe 10 - 15 seconds, by a gentle but powerful current. Then it would stop and they would get pushed over some other way for another 10 - 15 seconds.
    Made me realise some of the wavemakers we have do not really duplicate this, in the tank, they can send more of a sort of pulse, in comparison with nature. I think about the nearest thing to nature would be streams on an alternating timer. To really be realistic, I think more than two streams would be needed, to get more than just two opposing directions, and the time intervals should be randomly adjusted also.

          Well I got my stream, a 6100. One is all I need on my 50 odd gallon tank.
          It's awesome! Don't know why I waited so long. Pulled 5 PH's out of the tank, looks better already.
          I've got it pulsing, around 8 seconds on 100%, then a longer time on 30%. Makes a real good wave type action around the tank, really churns it up, but not too harsh on anything.
          Now I see why people rave about their streams.
          Anybody know what the lifespan of these things are?

            Alastair, that's a good point, but just their "feel" tells you that they're well made. Some of mine are over 1yr. & all are functioning as day 1 Bob

              IIRC Roger (Sales rep for Tunze) said that the drive unit (propeller, magnet, bushings, ect) is supposed to be replaced around 2 yrs. All the rest can last around 10yrs if taken care of.

                I run my Tunze Turbelle Electronic since 6 years without any problem. The Streams are online since 2 years.

                In this time range I only had to change the magnets and the propellers once of the Turbelle because they become noisy. After the change the problem was fixed.

                      Nick, I do not remember, too long ago.
