overflows

[mark]

My new tank, when I get it, will have smooth overflows and planning on gutter guard to keep the critters out.

It's going to be a room divider so overflow at either side, but if it was to be viewed only from the front, liking the idea of the shallow side to side overflow setup.

Have an interesting Excel spreadsheet from Reefs.org the gives gph plus height up each slot, you enter # of slots and width. Not sure how to put it up.
