I have a magnum 350 and I plan to do this:

And I have used the magnum before to get rid of cloudy water (but w/o the diatom powder) and the only problem I have with it, is the current it creates. No matter how I position the intake and out take it bothers the fish and messes up my plants.
If I use a container (like they did in the link), to keep the powder in the tank, will that help with the strong current as well?
