Haydite Substrate?

I'm seriously considering trying this. But so far I've only found one report of anyone using it, and am curious if there's any other Haydite users lurking out there.

It's inert, fired and expanded shale. It seems to have a very attractive combination of properties, which really isn't available in any other substrate:

1) Mixed color similar to pea gravel, but a bit darker; a nice natural look.
2) Available in a variety of sizes. I'm looking at 3/16".
3) Weight is more than Turface/Schultz, and close to Flourite.
4) The CEC of the bonsai grade is supposedly better than Flourite, although not as high as Turface.
5) Price seems reasonable. The report quoted $12 per 35lb.

It may be hard to find. But the bonsai shop mentioned in that report is just an hour away from me.

I've never used haydite, but I'm using akadama in a couple tanks with very good results. The major downside is that I'm used to planting in aquasoil type substrates now so when I try to plant in the hard stuff it's a real p-i-t-a.

It's a good idea and you've obviously done your homework. I look forward to the results if you decide to purchase it.

ps. you want some free montmo clay for a nice trace boost shoot me a pm.

Would love to see a pic of the akadama tanks!

I will definitely post a full report on the Haydite, if I can get it. Will probably be at least a few weeks to get everything lined up.

A bit of the unfired montmo clay goes at the bottom of the tank, I'm guessing?

Yeah, you sprinkle a thin layer on the bottom of the tank. It creates a great surface area for beneficial bacteria and has a really high cec (exact numbers are available on wikipedia). It's also a great flocculant and probably a decent trace mix as well, although I haven't managed to find any analyses.
