Thanks for the info RedForeman....

You ask if it is a new tank or an up and running one. The tank is in my
bedroom and I've been putting up with the noise of external filter units
for
years... I finally decided to just switch to undergravel (since it would
be
quiet) and be done with it. So, that is what I did... took off the
external
and install the undergravel. Was that an unwise thing to do? Anything I
need
to do differently?

I appreciate your help...
Jeff.

Ackhhh! Maybe it is just me, but I'd put the power filter back and let both
run for a while before removing the power filter. The UGF needs time to
establish a good bacterial colony under there. That's the only way it
works. I have a UGF and a power filter...
Good Luck,
