I'm curious, if they need £40 "salts", I have a big tub of Shrimp King "shrimp salt .. GH+ / KH+" and a little curious.
On reading - MgSO4 & CaSO4 in a 3 to 1 ratio is basically all that is required at about 1g per 10l.
This makes me think, if I use aged tap water and add the above 2 salts then the shrimp should do well.
A second thought was why not use carbonates as they will dissolve easily.
I drift - my understanding of chemistry is that salts that dissolve form an invisible suspension of the ion (metal, in this case Ca and Mg) and the cation (SO4) and they float about in the water separately only joining back together as crystals when the water boils/ evaporates. I MAY BE WRONG!!!! I did chemistry when I was 15 now 60... so maybe VERY wrong.
If something "grabs" the ions Ca /Mg then the water would tend to become acidic, H2SO4, and the spare O2 from the water would vent off, or be used elsewhere.
Then you have "fertilisers" so many ions & cations... I think it is best scratch my head, look at fish and plants if they look ok.
