to much water movement?

[draxlith]

i have a 22gal dwc system with 2 large air stones and i was thinking about adding a water pump that had a air line to a air pump running about 90 gph in the center of the tank that sends water and air bubbles out of the bearly breaking the water making 1 inch waves as well (no stream of water breaks the surface just makes waves and ripples) and i think has a nice spray of bubble

my only question is will the moving water damage or make it harder for the roots to catch O2 it's realy not much movement and it's directed up i think it might just push the roots to either side cause it's in the very center of a 22 gal rubber made tote??

heya drax,

imo the two large (12 inch?) air stones are plenty sufficient for the job, and you probably won't notice any difference running the additional water pump. in my setup i use aerospring, which is supposed to have the best oxygen distribution, but in all honesty i haven't noticed much difference when compared to a dwc, which i also have running.

now, sorry to not have answered your question yet. if you've got the extra pump laying around and you're compulsively addicted to perfection (like myself), then feel free to install the pump. from what i gather your water pump will be streaming water up and will be submerged just below the surface. a 90 gph pump is about as weak as they get, so this will not cause you any problems with the roots.
