Hi
correctly it was a french guy which add some salts in marine tanks to stabilize the system
Hans Werner Balling a german guy calculate a system which you can control Calcium,dkH and special trace elements which the corals need to grow.
This classical System works more like the 2 Part System
Fauna Marin developed then the system new and make it easier to use and for the modern reefer
This System calles Balling light
The different to the two part is that we work with much better cleaner salts 99,5 % and better
We did not use Epsom salt cause the sulfate will fallen out in reef tanks very fast.
and we use a special trace element mix which let corals better grow.
The Balling light system did not need to weight the salts or make
complicated mixes and it is for every system safe and useable.
The salt mixes together with the waterchange prevent an ionic inbalance.

Here you see another tank which use the balling methode
