sump design

[spikehs]

Picked up a standard 33gal tank this weekend and was gonna silicone in the baffles but before i did, i though i should check here first!
the baffels are 10inches high and would be configure like this:






-The baffles were from an old sump that i never hooked up, would 10inches be high enough?

-Is there an "optimal" space between the baffles that allows for the most buble reduction (really close, far...) and how much space shoud be between the baffle and the bottom of the tank (for the 1st and 4th oen?)thanks[/img]
