I have a 2213 on a 38 and had to add an airstone, by morning the fish were
at the top gasping, I have it heavly planted also and the spray bar moderate
fish load of a pair of rams. 4 corys and 7 guppies.

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.
