Interested to see your results.
I looked at some pics of the various ActiveFlora colors, and it seems to me I've seen a visually identical product in the past, sold overseas, and made from expanded shale. If I remember correctly, as that was years ago when I was looking at cheap alternate substrates. I did find a US-based aggregate manufacturer (Haydite) who sells and ships bonsai-grade expanded shale, plus a semi-local reseller. And one(!) person who tried it in a planted tank, reporting remarkable results. But the sample I obtained didn't look at all like what other photos showed, it was just way too ugly to consider using.
