I am in the process of setting up 2 135g setups. I have a pair of fx5 and a pair of ehiem 2217's. I plan to use 1 of each for each 135g. I have always used sumps and HOB filters so not 100% on how I layer these canister filters.
I thought I had it figured out until I saw this photo... it shows the ceramic rings before the coarse sponge filter. Is this the proper way of setting it up?

I currently have ceramic rings, biomatrix, 2217 coarse pad and filter floss.
