Should biowheel filter be making a 'big splash' for higher oxygen levels?

[Dave K.]

I have a Penguin biowheel filter on my 20 gallon tank. If I fill the water
level in the tank higher, so there's not as long of a "waterfall" coming off
of the filter, does that reduce the oxygen levels in the tank and is that
bad for the fish? Is it better to keep the water level lower -- maybe a half
inch or more below where the water comes out of my filter -- so that the
waterfall causes a bigger splash and possibly more underwater current or
doesn't it make a difference in the tank's oxygen level?

The more the splash, the more O2 gets in.....and the more water
evaporates.. You should get enough O2 in with the bio-wheel setup if
you fill to minimize the splash. I generally fill to the water is just
below the plastic trim on the inside. I do get a rippling affect across
the tank as the water enters.....

Depending on your bio load, adjust accordingly. If the fish are at the
surface a lot (that normally are not surface type) increase water
surface movement.....

Are the waves at the suface what increases the oxygen, or does the surface
have to be broken up more harshly with a strong "waterfall" or with bubble
coming up to increase the oxygen level?

You do not need a waterfall for good O2, but it would increase it. The
spraybar on the bio-wheel does a lot by itself. As long as the surface
of the water in the tank has movement, you should be OK... None of mine
have a waterfall, just a nice transition into the tank with the current
just under the surface.
