Black Diamond

  • We are currently upgrading MFK. thanks! -neo
I recomend blasting this black diamond material, it may contain metal though
 
I use this stuff and is awesome, fine with rays and bottom dwellers etc... To rins it out I just filled a plastic tub with the sand, filled with water, rinsed then pured away dirty water and rtepeated 3 times for each load, took a while but the stuff is quite dirty so needs it.
