crushed coral, what to do with it?

[peddy10181]

so i got a bunch of crushed coral that came with my 470gallon tank. i am going to be useing black sand in the tank. but could i use 50 pounds of it in my sump kind of like a DSB but with crushed coral? or should i just try and sell the crushed coral and go with a good old normal DSB?

i have a 50gallon trash can half full of crush coral lol.

I would get rid of the crushed coral and use white sand. Ive heard of added silicates in black sand.

I'd throw it in the sump... but thats me...

It doesn’t go bad and will work just fine for a deep sand bed, just adjust the depth depending on the coarseness of the crushed coral. A deep sand bed doesn’t have to be sand. I wouldn’t worry about the silicates in the black sand. The silicates are really insignificant and some animals in the tank need some silicates. Some one had a great right up about it in the last few months if I find the like I’ll post it for you. Then again if you just want something else just give it to someone else and get what you want.

CC is fine. I have used it for years. But black has added silicates from what I heard when I was doing FW. So I avoided it.
