Coral snow alternative

[Proteus]

Found this.
I also recall my father in law using bentonite in wine as a clarifier (floculant)
Bentonite clay does not affect your water chemistry. It works because at the ionic level it carries an electric charge which attracts other charged molecules. This attraction "focculates" (clumps) organics and other sub-micon fines around itself, which in turn then is large enough to filter or settle. This is how zeovit coral snow works - this is how the product I posted works. The difference is zeovite charges > $50.00 for 500mls of their product, while what I posted costs <$8.00 for the same amount.

This is nothing new - bentonite clay has been used to clear cloudy water forever. (its even in some of the salt mixes you buy) - it used to be called koi-clay. But suit yourself - good luck.
