Black quartz substrate

[kirstyflash]

We have a Cade400 set up bb atm with a few rocks, a terracotta pot for a pair of clowns, 2xgbta, bicolour Blenny, coral banded shrimp, alveo, purple stars, a few baby trochus and turbos. I don’t like the look of the bb. I have seen a tank with black quartz gravel and am thinking of putting down a shallow of it...1-3mm grains. Anyone had black gravel quartz? Pros and cons?

Cut piece of black star board to fit the bottom of the tank.

As in marine grade plastic?
