Filter Sock Question

[Cliff]

Thanks for all the responses everyone. I never did realize this could be a matter of preference. I had tried using filter socks on my old sump to stop micro bubbles from being sucked up into the skimmer. When I up-graded my sump, I put in a bubble trap in between the skimmer and the drain line from the tank. It’s eliminated about 95% of the micro bubbles and what little bubbles get through don’t seem to effect the new skimmer I have. I think I’ll just use the filter socks when I’m doing any kind of re-scaping in the tank to be on the safe side.
