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.
