We have had good luck with something as simple as this:

- -  water column
- -  plain gravel with laterite balls (Duplarit-K) at the base of plants
- -  ugf platform

Your scheme seems overly elaborate. I don't think the screen will keep
laterite from being pulled through the gravel by the powerheads.  The
egg crate (to prevent vacuuming the laterite up?) will probably cause
more problems than it solves (roots will get tangled in it and you will
have trouble planting things).

I'm amazed.  I would have thought peat would just lay there and
moulder.  Is this common with folks who have peat in the substrate?
