what is the most efficient way of putting calcium and other elements in a reef? also what the best to "set it and forget it" calcium reators are expensive and i am very confused on how the work, and 2 part dosing can be inaccurate, daily, and costly down the road. dosing pumps see to be the best of both worlds because its not a daily thing put you have to dial in the right amount of ml per min. What do you guess use and what would be simplest? thanks i hope this clears some things up for me.
