Montmorillonite a place in out tanks ? freshwater and marine

Presnetly it is used by the Japanese to line their Koi ponds to produce some of the best Koi in the world.
It is also used to provide minerals to Difficult to keep crystal red shrimps.
Scientific evidence exists to show that it aids the formation of lipids and RNA and has many beneficial qualities.
It is also capable of binding nutrients and floccultaing suspended Algae.
In fact the benefits seem almost endless and the addition of small quantities to a reef tank or a bed of it, where water can flow over it is of interest to me.

I can find no reference to its use on reefs but its worth noting that as a volcanic mud,it exists in many of the areas that reefs form, and is undoubtedly washed into the sea, possibly adding to the local mineral makeup of the water.

anybody used this on their ponds ?

wow, kb, it sounds an interesting idea, but to be honest I have never heard of the stuff. It will be interesting to hear what you find out though!
