Re: Hydroponic clay pellets as aquarium substrate?
I have never even heard of them, but you could run some tests by putting some in a bowl with water and testing the water after a few days. I suspect that they might have chemical additives that promote plant growth, but whether those additives are harmful to fish is a risk that might not be worth taking, in my opinion.
