Its definitely not an exact science as it very much depends on the components of the top soil you're using; which could range from rich substrate to nearly inert soil. In any case, the quantity of KCl to add is very little, and since it is added below the substrate it should be released slowly. It also depends on the type of plants and lighting you'll use and the ammount of nutrients you are going to be introducing in the form of fish food and/or ferts.
Experts, please correct me if i'm wrong!
