Depends. The idea behind the MCI is to have barely nothing in the water column. With the Kno3 protocol you can add exactly what you need and between 2.5 to 5 ppm will be in the water after plant uptake. In some cases you will need to add 70 ppm, in others 10 ppm. But the test is the ciano esencially, because if you run off Kno3 you'll got it.
About Tropica, well, they sell plants, if you add 7 ppm plants will survive for sure but you will need to buy a lot of them.
In the other hand, the MCI is a fertilizing and algae control method.
