Agreed 100% my online friend! Your point on the powerheads is well taken.
Its like taking a large scale surge device vs a powerhead. Its the way the
water is being disspursed. You could probably, in theory, surge the volume
of your tank mulitple times in the course of an hour, and every animal in
their would love it. You try and do the same with a powerhead, and you are
going to have an area where nothing will ever grow, then only something that
can handle a crap load of current will grow, and so on down the line.
It is discouraging to me as an aquarist, becuase it is impossible to
recreate that surge type flow that you see in the ocean. It is amazing
watching the ocean shows on tv, and they show something like kelp and it is
swaying back and forth. Traveling feet from point a to point b and back
again. That is whay corals in nature dont have the build up of detritus and
such like you can get in an aquarium.
Anyways, points well taken, and agreed with 100%!
