I have a cpr bakpak2 on my tank. I removed the biobale and use it for skimmer only. I was in a long term battle with algae and thought the biobale may be contributing to the problem. After talking to my LFS, they suggested removing it as they agreed it traps a lot of detritus. If you do leave it in, make sure to pull the biobale out and shake off the trapped detritus in tank water removed when you do water changes. The biobale is very coiled/springy and will splat junk all over the place when you pull it out of the bakpak chamber...just a heads up. I do have many more bubbles entering the tank now that the biobale is removed. You can rotate the return water outlet to face the side of aquarium to reduce bubbles flowing to other parts of the tank. My LFS also put forth the idea of replacing the biobale with soem chaeto and adding JBJ nano-light to the side of the Bakpak. I have not tried this but it is something I might in the future.
I also have a Aquaclear HOB
filter on my tank. The biomax substrate that comes with the filter traps much less detritus than the biobale.
