Silica stones for media?

[AJ Grottke]

I was wondering about using Maidenwell Diatomite in the GB instead of gravel or hydroton.  Also i have thought about doing 75% hydroton and %25 silica stone.  Does anyone have experience with this or have any input?

Hi AJ.  I think a lot of this discussion was covered in another one that happened about a month ago about Hydromite.  Check this out - http://aquaponicscommunity.com/forum/topics/higromite-media
