Turbulence and plants

See the thread "CO2 and Surface Agitation Debate", from 2/6/2003. Lots
of info/opinions there.

Hi All,
Just set up a new 55 gallon and planning to make it a light- to
moderately-planted tank, without CO2. I currently have an Emperor 400 on it
that is making more noise than it should, and I am going to return it,
either for another one or for a cannister (Eheim 2235). I would prefer not
to spend the money on a cannister, especially since opinions of the Emperor
are almost unanimously good.

My question relates to turbulence. There is *a lot* of it on the surface of
the water with the Emperor, and in my research I've come across some info
regarding turbulence being detrimental to plants (robs them of oxygen?).

How much of a concern should this be for me?

Thanks for any input,
Howard

To reduce that effect, fill the tank as high as possible. The
additional water will prevent the water from falling as far, thus
reducing the turbulence and the splatter noise.

Just a word of caution some tanks (like mine) will leak towards the
very top where the plastic edge meets the glass I had that happen and
it started a syphon and a little stream of water started running down
the corner of the tank and(it made a mess before I noticed even though
it was quite slow) it wouldnt stop till I broke the syhpon by taking
the water level down past the plastic edge...
