Re: [APD] Natural pea gravel, a high iron substrate
I'll second that!
I use a thin layer of local red clay, its everywhere in the south, on
the bottom then cover with washed creek sand/gravel. Costs me a whopping
$0.00!
And the creek is alot closer and has better hours than my local hardware
stores.
