Got a guy using http://www.bigriverind.com/pages/produc ... heet11.pdf

I think it was $70 by the yard. He picked it up in his pickup truck, standard 6 foot bed piled high with tarp tied down. I been thinking about it, but... You can get maybe 2 bags of LECA for that... you get 8x more of this stuff!

I think most concrete type places sell this. Stucco should start buying it and selling it in 50 Liter bags. Call it Stuccoton or Stuccolite or Hydrolite... idk, but it should sell like hotcakes!!!


IF you have some nice course sand somewhere, you can try that. I have always wanted to use course sand to try to rig up a good setup. Completely experimental though, and a lot of proper design would have to go into place. A swirl filter on the EXIT along with some other filters would probably be MANDATORY, but if you use physics right, it should be possible...
