Hello,
I have two (2) used bags of 3M Colorquartz in black. It is S-grade, which is the finest of the two that 3M produces. Used it in my 240G for about a month but decided to go bare bottom. Perfect for sensitive bottom dwelling fish.
The substrate is clean and already out of the tank.
Price is $40 FIRM, bring a 5G bucket.
Thanks for looking!
Best,
J
