I have this same chart done in Microsoft Excel. You just enter the gallons and it gives you the dosing in ml's by the day. It uses all of Excel's features so you can unhide the formulas and adjust them for your particular tank. It calculates the amounts down to 4 decimal places and rounds them up to one decimal place. I did this because most of us can only measure ml's down to one decimal place anyway.What do you guys think of seachem's recommended dosing schedule per their products. Is this a safe place to start? Also, they recommend using a few buffers on day 7, I've never added buffers and don't really want to.
