brs dosing instructions

[Baldy]

hello,

my tank ATM is low demand on dosing. I have a few corals, and all are softies so far. Regular water changes have been enough to maintain calcium and mag levels, bit not alkalinity.

I ordered a half gallon of soda ash from brs to begin dosing for alk as I'm going through a fair bit of reef fusion and want to spread it out a bit more. The thing is, everything I read says to dose equal parts of calc and alk. I i do this, I'll end up with quite high levels of calcium.

Is it ok to use the alk part only of recipe 1 2 part dose?
