Substrate For Corys, Again.

[KevinZ]

Hi. Before I start this thread I want to said I am sorry to make this thread, I know I have this thread alr long time ago.
I just found pet store that offer me This Kind of substrate and they said they keep their corys with this kind of substrate. I still Cycling My 66 US Gallon and I just want to hear about TTF member Opinion I made a lot of mistake and I realise that I have still A lot of thing To learn.
Anything should I concern about the Substrate for Corys ?

I caqnnot tell from the photo what the grain size is, or if it is angular or smooth.

You cannot go by pet stores, as they only intend having the fish for a very short period before they sell them. Once the fish are in your home tank, they are there for life, which can be 15-30 years for cories, and their substrate here is extremely important.

Kinda Triangular but I think I can use strainer to strain it?

Edit : I Try To Use the Old one that I bought and I Turn it Into Dust With Blender. is that safe?

To give you a good answer I would need to hold this in my hand. But you are probably OK.
