3M Color Quartz as a Cap and possible concern
Never used this stuff before, but I just received a bunch for free from a local aquarist. I like the way it feels. It is much softer than the pool filter sand, and plant substrates I have used and am using.
I currently have a mix of Floramax and eco complete in my planted tank as the substrate right now, and I was thinking of capping that with the 3M Color Quartz. I will need to do a thorough cleaning of the current substrate, since I have not syphoned the bottom for poop (mainly because I can't see the stuff anymore since I changed to the darker substrates).
Before I began cleaning the top of the current substrate, I started to rinse the quartz, even though the guy who gave me the stuff said I wouldn't need to. After rinsing it for some time, the water still seemed a bit cloudy, but not too cloudy, and my hands were stained a dark grey to black because of stirring the sand with my hands. After seeing this, I became concerned.
Is this stuff safe for aquarium use and my fish? I hear about people using this, but wasn't sure after seeing how badly my hands were stained. I plan on doing some more rinsing this evening.
