That day... is not today.
I just finished doing an 80% water change on my 20 high because I dosed it with 10 ml of Excel, when I should have dosed 2 ml. It could have been worse, though; I was on my way to dosing 20 ml when I realized, half way through, the mistake I was making. See, Amy and I had been talking about using a 10:1 dilution of Excel, to make it easier to dose our nanos. That thought was still in my mind when I calculated the dose I needed.
I will shortly be making up dosing cheat-sheets and taping them to the front of each tank, so I will no longer have to think when dosing, I will just have to measure.
