pH - 8.2
NO 3 - 2
NO 2 - 0.1
PO 4 - 0.1
Ammonia - 0.25
KH/Alk - 7.3 /2.62
Magnesium - 760 ?????
Calcium - belowe 290?????

I'm worried about my Mg and Ca???
 
Alk is low too. I use Seachem Reef Complete ( calcium and magnesium) and Reef Carbonate ( Alkalinity ). Just make sure you raise your parameters over the course of 4 or 5 days to the correct levels.
 
I use Red Sea Coral Pro salt and if you are dosing Reef Complete you are dosing magnesium and strontium too.
 
Ok, first things first! What is your salinity???
Low salinity = low everything else.
High salinity = high everything else.

What livestock do you have?
 
Livestock
4 clowns
Sailfin tang
Naso tang
2 chromis
Cleaning wrasse
Fairy wrasse
Six line wrasse
Fire goby

In that case it ia easy. Just buy yourself some alkalinity + calcium + magnesium dosing supplements & dose accordind to manufacturers specifications.
As mentioned before, spread it out over 3 days.

There is an incredibly good article by rhf about calcium & alk.

The magnesium is easy, just add the recommended amount over 3 days.

Gosh thank I'm so stressed. As I'm from middelburg no supply on marine products around. But I'll make a plan today. Thanks for the help again.
 
I see you dont have any corals...
In that case the low mag & calcium wouldnt be a major problem. Just increase it gradually to where you want it & test about once a month.

And another thing. Salt used for fish only tanks like seachem MARINE SALT (Not reef salt) has very low calcium & alk when mixed to normal salinity levels, so your tank will definitely be low on those 2 elements if you havent dosed anything...
 
Something doesnt seem right here. If you not dosing anything, i can understand your calcium and magnesium dropping to those levels...but then your KH should also be low.
