Fluorite

No, this is NOT the substance you find in your toothpaste;
that's Fluoride (with a "d").


Fluorite is the name of the gravel that was added to the RH Fish Tank today. A layer (6kg worth of it) was sprinkled over the existing gravel so that it now looks reddish and darker than the previous gravel which was Lapis Gravel which looks like sand from a lousy beach.

Comparison between Lapis Gravel (top) and Fluorite (bottom)


A card was used as a tool to insert Fluorite between the Lapis Gravel and the sides of the RH Fish Tank, making it look as if the whole tank was filled with Fluorite gravel; actually only 6kg out of the 46kg of gravel is Fluorite. One side of the RH Fish Tank (next to the white water cabinet) was left un-carded so you can see the old and new gravel in two layers. The reason for adding the new gravel (the brand is Seachem, for those who might be interested) is to give the tank a more contrasting coloured look: green plants will stand out more, and the coloured fishes will look more alive!
