Balling salt purity

[Aqua-Digital]

Fauna salts are tested for purity by a chemical lab in Germany batch by batch, I do not know any other manufacturer that does this, so there is no question in regards to the purity.

In regards to a "crapshoot" not quite sure what you are referring to, but to start the system off -

Test you paremeters
dose 50ml of each element
Wait two hours
re- test

Now you know how much 50ml will raise you systems levels by and from there work out you dosing.

Re test daily for the first week to fine tune until you learn your systems draw and then test bi weekly after this.
