Hi All,
I recently replaced my power filter with an Eheim 2217 on my 55 gallon,
well-stocked, moderately-planted tank. I have a concern that the spray bar
output might be too powerful for both the fish and the plants, so I'd like
to get some input from the group. Currently I have the spray going straight
out across the top, just below the water surface. I found one post from a
long time ago suggesting pointing the spray down towards the glass, but that
doesn't seem to have a major effect on my two issues....

The smaller fish in the tank (rosy barbs, SAEs, even the smaller gourami's)
seem to get pushed around by the output, but OTOH they keep going through it
when it is possible to avoid, so maybe they like the current?

Also plants in the vicinity sway in various directions. Is that good, bad
or indifferent for them? I don't do the CO2 thing and my main focus is the
fish, but I like the small variety of live plants and want to keep them as
healthy as possible.

Thanks for any input.
Howard
