When I received mine in the mail I thought to myself...damn that's a big box for a filter.... I thought I paid more for the empty space inside until I opened the box and was looking for the empty space!
Its recommended to not use polishing pads or any fine particle filtration pads in the center baskets. Instead replaced the coarse sponges with 20ppi reticulated filter foam. You can get it from my Sig.
This will eliminate the micro bubble issue.
This also happens when you are using a high density bio media.
