At water change time I stir the sand up with my hands by digging in it with my fingernails. Alot of sand ends up under my fingernails and I don't feel it. The sand under my nails easily comes out when I run my hands under the faucet. If it was sharp I'd think it would "stick" there.
Maybe if I had done TONS of research prior I would have gone with a different black sand but I highly doubt it. I'm approaching one year on my display tank (June) and knock wood, everyone in my tank is healthy & robust.
There's a thread somewhere here from a few days ago where BTMS is discussed in detail. I need to go find it...based on reading that thread I knew my choice of BTMS was perfectly fine.
You are right, those loaches and cories are more sensitive than you. it wont cut your hand like it will their flesh bellies, imagine a bunch of tiny papercuts. Thats if its as coarse as they claim, get a magnifying glass and check it out if you dont have access to a microscope.
No attitude given in the typing of this reply. Dont take it that way.
What the TMS is saying from caribsea is that its not ok for burrowers or bottom dwellers, I think this is because of what black sand is derived from, Iron. Iron is sharp when its super small like that, we cant feel it because of our textured fingers but try a little on your wrist or tight piece of smooth skin on your body, maybe between toes? you will notice a difference in the feel of it.
Anyone who has ever been to the beach can verify.
