Hi everyone,

I am considering setting up a automatic dosing system in preparation for buying more corals, I have a 120g tank, running for 10months now. Contains around 10 fish, 5 soft corals and 6 LPS corals.

I've measured my calc, mag & alk for the last 3 days at the same time and it's come out as follows.

Calc - 420 / 420 / 420
Mag - 1260 / 1260 / 1260
DKH - 7 / 6.85 / 6.7

I know my alk is too low but as it's dropping steadily should I start dosing just alk and leave the others to water changes?

I change 15% water every two weeks with red sea salt.
