i actually sanded mine down, so it is pretty rought. i stopped running mine because i needed the powerhead in my main display to get more circulation near my sandbed. i think if i had left it going, i would have similar results to sasquatch.
what i mean squatch is, did the stuff that normally grows on your sump baffle stop growing since this stuff is taking its nutrients? or was it too small to produce and impact?
