I picked up 80 lbs of quartzite for my 75 gallon that I'm setting up from scratch. The stuff has been washed and scrubbed and is currently sitting in a bleach bath. Some of the pieces seem to be showing rust now that they've been drenched. Will this be a problem for African cichlids? There's also plenty of shiny flakes stuck to the rock. Maybe mica? Maybe quartz? Is this okay?
