Daily microbubble tank treatment?

So I've seen some interesting things floating around Facebook of all places on a couple different Reef pages. There seems to be quite a few people who are running air stones right at the return pump in the sump to create essentially a skimmer out of their whole tank for a set amount of time every day. In theory it makes a lot of sense, but I can't seem to find much on any forums. I've always been told to AVOID microbubbles? Does anyone do this or have any input/knowledge on it?

Thanks in advance,

Blair
