Hey everyone,
I recently upgraded my setup to the Waterbox Peninsula Mini 25 and I have a custom made glass lid, so the only place I can mount a protein skimmer is in the back filter / sponge compartment. The rest of the lid/top is closed off, so options like hang-on or top-mount won’t work for me.
I’d love advice from anyone who has done this successfully on this/other tanks..
List of questions:
Which models have you used that physically fit inside the back (filter sponge / filter sock) chamber of a Peninsula Mini or similar dimension tank?
What are the base widths, depths, height of skimmer bodies + collection cup needed so it fits without knocking plumbing, hoses, or overflow?
Noise/practical usage: do silent/quiet DC nano skimmers work well in that tight space, or do they struggle?
What media are people running in their Waterbox Peninsula (or similar filter compartments)? Sponges, filter socks, carbon, GFO, bio-balls, ceramic rings, etc.
Has anyone found a good way to cover the back filter sponge compartment?
I’m worried dust and kitchen oils might be settling in there, since I’ve noticed a light surface film forming on my display.
