Agreed... but for the sake of simplicity, lets say we dose 20ppm of K each week, and only 5ppm is consumed at the end of each week... Also assume a 30% water change weekly
Code:
week1 start K = 20ppm end=15ppm water change = 10.5ppm
week2 start K = 30.5ppm end=25.5ppm water change = 17.85ppm
week3 start K = 37.85ppm end=32.85ppm water change = 22.995ppm
you can already see that the level begins to taper off... if you keep this up for 10 weeks you should basically see that your K level tapers off at about 54ppm at the start of the week 11
More importantly, the % of water change greatly affects this level... i.e. if you did a 20% and 40% water change respectively, you would find the K levels tapering off at 79ppm (20 weeks) and 42ppm (9 weeks)
