Black diamond blasting media.

[1077]

Good morning all,
I am considering tearing down my low tech 80 gallon tank and re-doing substrate, and am welcoming thought's or expieriences with.. " Black diamond blasting media" to cap osmocote, soil,peat mix with.
I very much like the balck sand I have in smaller tank which was purchased at LFS but,, is too expensive for me for larger tank.
Product is said to be coal slag which also contains Calcium,Magnesium,Iron,and I can get 50 lb bags from "Tractor supply" Co.for around six dollars.
It may be a bit sharp for cory's, but I can move them to another tank and am wondering,, what say you ?
Many thanks in advance,
Lee.

I Like It

Hi Lee,

This stuff is actually less coarse than many of the sands people use.

It breaks down readily and does not seem to scratch the glass.

Keep an eye on your Corys but I think they should be okay.
