dosing?

[mattbryant2]

when is it necessary to dose? how do you know what to dose? and how much? is dosing required with every reef tank?

The ONLY time dosing is necessary or recommended is when something tests low. ALWAYS test first.
With regular water changes typically calcium is the only thing that needs to be dosed and maybe a buffer.
Get some test kits for calcium & alk, test the water and go from there.
