My test results

Nitrates 5
Calcium 520
Magnesium 1500
Alk 6 DKH

Im new to this testing, this is my 29biocube readings.
Is there a problem here besides nitrates?

Do I need any aditives?

Thanks

The alkalinity is rather low. I'd try to keep it at 7 dKH or better. The other numbers are acceptable. These articles might help:
