this is actually a harder grade of limestone and the best source is Kotputli in Rajasthan,

i have it in one tank but was actually looking for something blacker.

i had already thought to use this if i get nothing else.

if some one wants this I can get the only difficulty is in sieving the finer stone dust and then washing it.

looks like crushed slate

it does appear to be crushed slate. Harmful for fishes due to the sharp edges of this substrate

Sorry Ishaan in this thread I cannot agree with you as I know what this is.
also if rounded edges are wanted then we would need to drum these. and I an sure because I have been purchasing this stone for our concrete plant since 2010.

My guess is also crushed granite and as aquascapist mentions it did not change water parameter I would doubt if it really is limestone. But Vishal seems very sure about what this is, so I shall give him the benefit of doubt

can we get fine black sand or the darkest brown sand in delhi/ncr at all?

On indiamart there are many companies doing sands and aqua sands. Not really sure if they are suitable for fishes or not?
