1/4 tsp of K2SO4 every day in a 200L tank is only adding
23.59ppm of K per week. That's definitely not an extreme
amount. Combined with the K from the KNO3, if the KNO3
is added 4 times a week, it would total 34ppm. Probably
a little much, but I doubt it is enough to trigger a problem.
Myriophyllum is typically an easy plant to grow, and has never
been bothered by occasional overdoses of nutrients in my tank.
