I created a calculator for calculating the results of water changes in the "Water Changes" section. All data is in ppm. Input data: Aquarium volume: this refers to the volume of water. Initial value: the parameter value before the first water change. Change over the period: this is the natural change in the parameter during the period between water changes. One-time change volume: the amount of water changed in liters. Number of changes: how many periods of changes to build the graph. The specific period is not important; it can be a week, a month, or a year. The main thing is that the natural change in the parameter is taken over the same period. The calculator accounts for both negative - consumption of the substance, and positive - accumulation of the substance.
