Tips on removing micro bubbles from skimmer in sump

[zico]

I m now designing my own sump design for a new tank.

From my skimmer compartment, the next compartment will be the return pump.

Am worried that since the Skimmer and Return Pump compartments are next to each other, micro bubbles may emerge from skimmer and go straight in to the tank via the return pump.

1. does reefers here have a similar sump design? Any problem with micro bubbles?

2. i intend to put filter socks on the Skimmer outlet. would this greatly reduce micro bubbles output ?

Thanks.

you might want to try putting a course sponge at the skimmer outlet, it does wonders when it comes to eliminating microbubbles.

A finer sponge would work too, but it traps dirt a lot faster and that would cause the water level in the skimmer to rise past the set point.

Thanks for advice. I added a filter sock to the outlet of the skimmer. So far so good.

Besides trapping microbubbles, it also seems to work well as an additional mechanical filter. Its been there for about 5 days and there are some light brown stains emerging on the sock.
