Too much water flow?
I have a 20 gal
tank and have two powerheads. One is a Aqua Clear 402 (inherited from a coworker and can pump 270 gal
/hr) and then I just purchased a rotating Powersweep 214 (max 160 gal
/hr). Is this too much for my little tank? I have some small featherduster like organisms on my live rock and they are swaying like mad!
I have the larger of the two powerheads on the left back side, about 3/4 of the way down the tank facing the center of the tank. The smaller rotating powerhead is about a quarter of the way up on the right hand side of the tank.
In the way of livestock, I have some hermits, snails, an emerald crab and a spiny urchin. I just changed out the crushed coral bottom and am giving everything time to adjust before I add the fishies.
Thanks a bunch!
