Even if you have to pay more initially for the skimmer, this saves money in the long run. Why buy twice, what you only need to buy once.

This is a function of the width of the baffles. I flow roughly 2800 gph through sumps, with 1" drop from skimmer section, and often 4" drop from a "fuge" section (far less flow rate though), into the return section, without bubble problems, or appreciable noise. Again, size matters when it comes to flow rates.



In theory your correct. However many many people dont buy the best skimmer and therefore have to upgrade later. So designing your sump with any future upgrades that you may want to do is not a bad idea.

As far width of baffles.... That has nothing to do with what I was talking about. I am not talking about micro bubbles from the drain or skimmer. I am talking about bubbles you can get when the water drops over that last baffle and falls into the return section.

My return is only about 800gph and the return section is 8 inches deep and if my water drops more then about .5 inches the pump will suck those small air bubbles in before they can surface.

Again just something to think about.
