As I cleaned the FX5 today it's true it still in my mind is just as when I started this thread. I only have the C530 here to compare it to. The FX is a smaller filter. I'm sure the EHEIM 2262,2080, Rena XP4, The Marineland C-530 and its knock off's all are larger and again I'm no scientist but there are a Ton of studies out there that claim surface area, volume, to be as important. Another thing I noticed is the way the trays are made if you use no premedia to increase flow then all you have is just Bio clear to the bottom and back into the tank. Now I've seen a few ways to modify the trays and get rid of some of those side sponges that to me do next to nothing(I have the same issue with the 406 side sponges, when I clean they hardly need to be touched. So im cleaning to much or there doing nothing). Someone chimed in last night and mentioned a way to reload the trays with some modified material? I just do not want to alter the filter itself at this point. I swear I don't kow why I do this to myself!!! I open it up as above and expect you all to be nice and friendly.....I understand many are into this filter and can get upset when someone puts it down. So if I'm going to get my ??? chewed all I ask is at least try to give me ways to reconfigure this filter from stock to change my mind?
