My water parameter

[YayItsCola]

Calcium 360 ppm
Alkalinity 12 dKH
Nitrite Undetectable
Nitrate Undetectable
Phosphate 0.25 ? [Used Api test kit for this]
Temperature 78-79° F
Ph 7.9-8.2


I think my calcium is a bit low, is there anything else wrong?

What about Mag?

I keep my CA around 450, ALK around 8-10, and MAG aroud 1500. With phosphates, id try to get them to where its zero, even through with most test kits its not a true zero.

what are you using to measures mag or what kit do you recommend me using and is it bad to have to much alk?

[arts007]

What kind of tank do you have? Fish only or Reef... if reef then I would get a Salifert test kit for the magnesium. 1400-1500ppm is a good range, Calcium around 420-450ppm and dKH around 8-10 as stated.

[YayItsCola]

Yeah reef and how do I lower alk?

[arts007]

Give it some time, it will drop on its own as corals use it

In general, you should shoot for Mag around 1350-1400, Ca around 400-425, Alkalinity around 9 (natural sea water is slightly less) But it is important to measure all three.

If you are unable to locate a Salifert Mag test kit(seem to be on backorder at most places right now), Elos is apparently another excellent choice, which was recommended in Reef Chemistry.

got a mag test from marine depot last week.
