Seachem Flourite - saltwater?

[Dan Huynh]

Can't seem to find any information on this so I figured to ask all the experts in here for advice. I had just broke down my discus tank that I used to have 15lb of Seachem Flourite as a substrate, does anyone know if I can use this same substrate for a saltwater reef tank. Thanks.

I'd be worried about Al3+ leaching since it is clay based
