Does anyone know where the cheapest place is to buy expanded clay balls? im located in Sydney

Ring around hydro stores, there will usually be specials you can find.

But if you want cheapest, get some gravel.

Hi there Barra

I live in the uk but I found that if you find a specialist aggregate store online, they often have damaged 50L bags of clay balls. They then empty the damaged bags into 1ton bags and sell at a very good price.

Hope it helps
