Sand sifting goby and black diamond blasting sand

[Heehee]

Does anybody use black diamond blasting sand? I had a yellow watchman goby and he disappeared after 2 days. Later that week I found his body. How likely is it my goby couldn't survive because of my sand. Black diamond 20/40

Is that not coal slag?

If that's the stuff im thinking of, it's pretty sharp edged, I'd think it might be a problem for sand sifters.

So I want to start out by saying I have never had a sand- sifting goby. However, I have used blasting sand in several tanks with the same results, both freshwater and saltwater. Both did just fine, and I never had any issues in my reef tank with blasting sand. Now, I will admit that I am not an expert, however, I know a little bit more about blasting sand, given my experience not just in the aquarium, but also using it for work for about 7 months. A lot of people are still under the impression that blasting sand is sharp, but that's not true anymore. In the old days, you might have a sharpness. Nowadays, there isn't much of a difference between normal sand and blasting sand when it comes to sharpness. The only thing you have to look out for is the fine or coarseness of the sand. Bottom line--20/40 would be a good, cheap substrate for your tank and I do not think the sand was the cause of your goby's death.

Coal slag if full of toxic chemicals such as beryllium which is very dangerous.
