What can I do to rasie my calcium, alkalinity and magnesium levels

I tested my levels today and I am low on my magnesium (930) alkalinity-8 and Calcium (280)
My tank is new, set it up Feb.17 and it completed its cycle last weekend, for the last week of testing everything stayed the same for Ammonia 0, PH 8.2 , SG 1.023, Nitrite 0, Nitrate 0

What products do you recommend to bring my levels up for the Ca, KH and Mg? Whats the best brands etc...?

My tank is a 75g with a 30g sump

ThankS, Rich

 

First get your Mag up. A couple cups of epsom salt should do it. Add 1 cup (mixed in water) at a time, then test again a little later. 1 cup won't over shoot it in your 75g.
Add Calcuim and baking soda as needed, according to the 3reef calculator, depending on what calcium product you're using.

 

Since your system is new, I doubt that you have any corals, you dont have to worry about Mag, Cal and Alk as of yet. When you start adding corals, then worry about those elements. For now, just check the following; SG, Nh3, No2, No3, Po4 and temp.

When your ready to start supplementing, there are lots of choices out there. Everywhere from already made to home-made supplements. Luna

 

Yeah....that Mg needs to come up first. Then Ca, then dKh. Do this slowly over the next several days. By the book the Mg is no more than 100ppm per day, Ca no more than 25ppm per day and I generally do not raise my dKH by more than 2 or 3 points per day (I have never found a number representing a max). If you do things too fast, the pH can fluctuate. I try to keep my levels, just a point of reference....and this varies from aquarist to aquarist at

Mg: 1600
Ca: 480
dKH: 12 to 15
