New to Dosing Ca, Mg and Alk...and would like some advice

[e46er]

PH @9 is wayyyyyy to high 7.8-8.3 is an acceptable range

When u start dosing measure constantly over the first week
Or 2 to make suttle adjustments

Dose cal and alk at different times so you don't get precipitation

I think he meant Alk

For what its worth, in my experience I wouldn't try dosing any Ca or dkh until my Mg was closer to 1400-1450. Your Mg levels is what's going to determine how much of your Ca and dkh will stay in solution. In my tank if my Mg is below 1300 or so my Ca or dkh won't budge no matter how much I dose. Again, that's been my experience.

You having any calcium deposition on equipment? Any precipitation of calcium?
That Magnesium seems awful low, and with your sps and use of ca, agree you need to first increase mg, otherwise other parameters wont go up

Mind you, if your tank looks great, dont panic too much
Go slow, be observant!

Agreed. If everything is alive, growing and looking good, all these numbers are just tweaking your tank, optimizing it.
And I love the BRS calculator for how much to dose for these parameters. Keep a close eye on what the recommended rise is for each parameter and raise levels slowly.

Didnt see your salinity either
Lower salinity will definitly reduce mg
Thats an easy one to fix
