100% Flourite or 50% Flourite with 50% black sand???

After some tedious washing, I finally managed to get the flourite to run
clear in the sink. I used a plate and my python to fill the tank slowly. I
found the tank to be slightly clouded but cleared up within a few hours only
I put my aquaclear to work.

Phil..

It took me five hours to wash two 7kg bags of the stuff. I hardly had any
suspended material at all. It was nothing like the red soup I had the
first time I did a tank with flourite.
