well i have his windows calculator and if i change it to just add the amount directly to tank...i need to add about 4.39grams of K2SO4 to the tank (made it so that it was a dose for about 52 gallons 197 liters). the teaspoon way, it gives me around 13.68ppm per dose. which over a week would be about 27.36ppm. which is above the suggested but idk if it would hurt anything..
so how would i go about dosing directly into the tank, can i just take a cup of tank water and then add to that, and dissolve it in the cup then pour the cup back into the tank and rinse it out in tank water?? is that about how im going to have to do this? cuz i really dont want to just add it in the tank and have the fish eat it or something.
