New aqua fx octopus problems

No problem it confused the crap out of me at first too.

I have a good understanding of how a basic rodi filter works, but the second membrane part is a new concept to me. I knew they could be used but I never looked into it very much.
It wasn't until you mentioned it that it got me thinking I should add a second membrane.
