Okay, I've finally scrounged around 20 LFS's for 4 bags flourite after
much
difficulty in finding it for my 38G, so when I remove my UGF to transfer
to
a flourite substrate medium planted tank will I need more aeration via a
powerhead or other aerator during the night or will my Eheim 2213
cannister
filter spray bar be enough to keep up with the fish and plants oxygen
needs
if I have it just above the waterline spraying against the glass.



Try putting the spray bar about an inch and a half to two inches below the
surface of the water pointing upwards at a forty-five degree angle. I had
mine running across the level of the water, but then changed it like this
and got much better surface agitation.
