protein skimmer for the waterbox cube 20

[jbeatts]

I can not find a protein skimmer that will fit in the Waterbox cube 20. I had a Hydor Koralia Nano-Skim Internal Protein Skimmer which fit in the back and worked well, but restricted water flow causing the pump to run dry. I ordered another skimmer thinking that it would work, but the dimensions did not include the suction cups so it ended up not fitting. Does anyone know of a protein skimmer that will fit in the back chamber of the tank?

Has the manufacturer made any suggestions for this problem?

Try contacting them, surely you are not the only person with this issue! They probably have some good ideas.
