You're confusing black blasting sand with white. Black blasting sand is made from iron ore slag and is sharp and I don't recommend it for most tanks.under_control said:YEs. It is inert.
Silica sand and blasting sand are NOT the same. Blasting sand is sharper and dirtier-it is also a byproduct and is hard to guarantee it is safe--but I've used it for years with absolute no problem. I wouldn't use blasting sand(ie black magic) with sand sifters like many africans and many ca/sa fish.
where do you get silica sand and how much how much would i put in a 55g tank srry for all the questions new 2 cichlid tankingDanniGirl said:Agreed.
I have silica sand in my tank and the cichlids love it. My only advise, WASH IT OUT WELL. -To the point where the water runs clear when you sift it. :wink:
