If you are planning on using a dosing pump get your calcium,akalinty and magnesium to correct levels before dosing with the pump. Don't try catchup with the pump or you will have issues. Once you get levels where you want them go 3 days witout adding anything and then test. Determine what your loss was with each element and divide by 3. This will tell you your daily intake. Once you do this then go to one of the reef calculaters like the brs one and it will tell you how much to dose to maintain these levels.Then you can set doser accordingly. I made this mistake and had my parameters all messed up. Live and learn. lol
