I had the idea for the UGF and went to the invert section to inquire about the 12 long I want to build and Mordalphus, shrimpnmoss, and others quickly chimed in telling me about the bio media, etc., but if shrimp like clean water then a tank with a spotless substrate makes common sense and to make it your bio media filter bed is just smart, bigger is better.
I have like 6 of the Filtermax 3 pre-filters that you have pictured here.
Work great, resist clogging pretty well (it is more like pond filter foam than fine pored aquarium filter foam) and the shrimp seem to love to pick at them and feed off of them.
I can just see how some people would not like to look at them. I don't mind one way or another but I don't have show tanks (or even aquascape the tanks) so aesthetics aren't something I can comment on much.
