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

Presumably it’s kept clean enough by the pre-filter.

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.

Yes, that’s what I do.
