Is there an "optimal" height or location for a powerhead on an undergravel filter? Top or Bottom of Tank? I just started this tank and the pet store owners were divided from the powerhead manufacturer.
Manufacturer of powerhead shows and indicates placement near the top of the tank for maximum suface turbulence (i.e. oxygen introduction), the pet store owner said he prefers his powerheads a few inches off the bottom.
Your thoughts?
