MitchM tank build

[MitchM]

Hi Kevin,

The holes in the top are 2 1/4", the holes in the back are 2 1/2".

That's a good point about the heaters. I wonder how much heat the tank would lose? I heard that acrylic had some insulating properties, plus I'll also be using lids on the tank.
I'm not too concerned about the temporary loss of filtering at this point. I don't want a heavily stocked tank. The tank feedings could occur near the end of the rest cycle.

If I went with your last setup suggestion, I would still need to drill a couple of holes for the sump return, wouldn't I?
