In the past I've tried to keep those really colourfull bright blue sponges a couple of times. First when my tank was Berlin only, and a second time when it was on the ZEO-method. I figured I would have more luck with Korallenzucht's "Sponge Power". I had it a bit longer the second time, but still couldn't keep it.
Now that my tank has a scrubber... Should I try again?
Does anybody have any experience with keep the blue sponges on a scrubber-based system?
