How damaging are microbubbles in a Fish Only (and few invert) tank?

[kingkapoor]

I bought this for my fish only, sumpless tank. https://www.marinedepot.com/eheim-s...zj09trfsZNooyDK-DjGCXPbWqgiLyfRoCffIQAvD_BwE&

I love it as it keeps the oily layers clean but it does spit a lot of microbubbles into my 50 G tank.

Are the microbubbles for the fish bad at all?

Nope they wouldn’t care less
