Just set up automatic dosing of Calcium, Alkalinity and Magnesium with my Marine Magic doser and made a huge woopsie..

Thinking that the first time setting on the first pump was the ON time and the second time setting for the same pump was the off time I plugged in..
Pump A
18:00:00
18:00:15

..thinking that this would turn the pump on at 18:00:00 and off 15 seconds later at 18:00:15.. WRONG! The second line is for the length of time you want the pump to run when it turns on at 18:00:00! My doser was set to pump for 18 hrs LOL. By the time I came by to check on things, 3.5 liters of Calcium solution had been added to the tank. Calcium shot up from 400 to 800 in about 2 hrs..

Luckily for me Alkalinity and Magnesium stayed in check at 7.5 and 1300 respectively and I do not have a snowstorm of precipitate in the tank and everything seems to be doing okay still. I did a 10% waterchange or so as that is all the water I had made up. Hopefully things will be okay and nothing is hurt too badly..

To my defense, the instructions for the doser look to be written by a 12 year old from China who has never spoken a word of English but still, just a reminder to always check, double check, triple check, and check again when it comes to things in this hobby.
