Flourite is one of the dirtiest substrates, which is I tend to rinse it for an hour before I add it to a tank. One thing I do is I'll hook up extra filters to the tank to help clear the water, and I add polyester fiber fill to each filter to catch any tiny debris that passes through any filter pad.
You'd get more answers, and suggestions by posting a similar thread in in the substrate forum.
