Hi Justin,

I have A 55 set up simular to what you describe. A little  Laterite, with
flourite and gravel from a previous setup. To it was added some peat and a
small amount of topsoil in the bottom layer. The plants are doing great.
 Neil the fish are too.  8=} ) It has 220 watts of VHO and CO2 injection.
You are welcome to drive up and take a look. If so I'll send you my phone #
so you can get directions and set up a time when I'm Home.

Best Wishes,
