Been thinking about using colorquartz for a while now. Have a 55 in my fishroom that I wanted to plant and use for some Discus I was getting. Decided to go with the black colorquartz T grade. Picked up a couple of bags earlier this week. The tank was barebottom and already cycled so I rinsed the colorquartz really, really well and put it in the tank. I was stunned. Without a doubt the best looking substrate I have seen yet. I have tanks with Eco, SMS, Truface, pool filter sand and pebbels, none begin to compare. Then I started adding some plants. The green and the very black colarquartz contrast beautifully. A couple of pieces of driftwood looked even better. I should have listened to lauralee a long time ago. I love this stuff. I will use root tabs since it is inert along with some ferts in the water column.
