My tank was even more opaque than this.

48 hours later it's looking like a disaster zone.

All the surfaces of the plants, gravel, etc. are covered with a thin powder 
of white.

And I lost a glo-light tetra as well.

So I've done 2x 75% water changes and I'm vacuuming up as much as I can.

Can't be doing their gills much use as I see from the bottle containing the 
powder that it's labelled as a Irritant.
