NO3:PO4

[takeastabatit22]

Any one out their use red see nopox?
I used it to a year no problems. Then weaned my self off it. After a couple mouths I couldn't maintain low no3. So I started back on it. As expected. It's doing a good job. But I'm am getting cyanobacteria again. I noticed while off it was all gone. Now tank gets just covered again.
Is this the imbalance in nutreances?

Salinity 1.25
Temp 77
Alk 8.4
Cal 430
Mag 1340
No3 2
Po4 0.03

Is this normal? I had it last to.e also.
Any tips? Or exsperance?

Ultimately would love to be off it. But tank seems to run too rich in no3
