Dennis thinks an extra weir wall is the best bet for adding a substrate.
So now the question is where would you get a piece of acrylic to glue in there?
Anyone know the length and thickness of the other weir walls?
How high would be optimal for the wall to (a) keep the sand/mud bed (let's say 1-2" bed) in place, and (b) keep enough flow in the bottom of the space? Maybe 4 inches?
I'd prefer no powerheads in the sump but could add a small one if necessary.
Thanks!
