Excellent idea (as were the others I received). I need to scout around to find a place that will drill the spare tank glass (not sure they exist, out here in the wilderness {central Penna}). With that set-up I couldn't go "over the wall" and use a syphon effect to draw the water to the lower sump, for fear that if I lost the syphon the refugium would overflow while the sump powerhead kept on pumping water to the refugium. Maybe I can use a "T" valve somewhere upstream of the sump to provide water to the refugium, then everything would be gravity fed. Hmmmm. That would still require one hole drilled. Might as well get the 2 done, assuming I can find someone that does that around here.
Thanks again,
Larry

Another way to do it, if you have room, is to link the sump to the refugium.
If you can raise the refugium above the sump, then drill the refugium
towards the top so it acts as an overflow back into the sump. If you drill
it, you can install a bulkhead and then plumb it back to the sump. Then you
can pump water directly from the sump, into the refugium where it will
overflow back out into the sump. No worries that way. Problem is getting the
top of the refugium higher than the sump.

LEAVING THE LIST
================
To stop receiving messages you will need to send a message to [EMAIL PROTECTED] with a command to remove you from the list. The list manager controls who belongs to the list.
For example:
--------------------------------------------------------------
From: John Doe <[EMAIL PROTECTED]>
To: [EMAIL PROTECTED]
Subject: <not needed>
UNSUBSCRIBE
--------------------------------------------------------------
