Backyard Aquaponics
A place to discuss aquaponics

I can buy expanded clay from where I work... Its used here in place of pea gravel in making concrete blocks (called light-weights)(they weigh less and have better fireproofing ratings)
They buy it by the yard (1 cubic yard=3ftx3ftx3ft or 27 cubic ft)
What is a good price ???

lol if your boss buys it by the yard, why not ask him?

Dont think there is any american hydroponic experts here, australians work in cubic metres.

Well you have just made a lot of friends in your area

There are different grades of expanded clay.. It will be different to normal hydroponic expanded clay most people are using.
