*** got 2 powerheads running in my setup about 6" below the top of the tank. Would it be better to have them lower to move more water across the bottom? tank dimensions 48"Lx24"Wx30"H

Thanks :thumb:

I would put one where it breaks the surface of the water for better oxygen, and then one lower in the tank to circulate the bottom water. water movement water movement water movement!

If you have adequate filtration then water movement at the bottom shouldn't be a problem. I put mine facing my HOB or Canister output. The water coming out of the powerhead hits the water coming out of the filter. This causes a nice break in the water and also pushes the water down for movement on the bottom.
