I initially bought a coralife skimmer months ago. I used it for about a month and then took it out. I put it back in today and microbubbles are flowing into the tank. Should I be concerned? There’s no other good place to place it because it’s truly intended to sit in the 1st chamber of the 32g biocube. I’ve been doing fine without it but curious if I’d see any benefits from it if I stuck with it longer than last time.
