A fellow local plated tank enthusiast offered me 115 lb of black and red flourite, not mixed, for $60. I estimated that it is around $150 in flourite. So am I right in understanding that flourite is mostly inert and there is no problem in buying used flourite. If anything it is already washed, which I here can be a task in itself.
