If Hel-X is biological media why have they put it in the bottom?

It would make sense to put your biological media closest to the source of the substances you want to biologically process, no?

That said, I like to put foam in the first tray to catch any detritus or mulm that escapes the prefilter, keeping the rest of the filter relatively clean.
