ICP Test Re

[Niknak36]

ICP Test results, was considering increasing sulfur, any thoughts please?

Try to get salinity up first to about 1.026 Then Correct Cal, K, & I. I’d let Alk fall a little, and increase the PO4 to around .06 ppm. Probably change the RODI filters so nothing is making it through. Don’t worry about Si too much. It’s pretty much harmless even if 2-3 ppm ++

Cr, Co, Fe, Zn, Ni, V…I would avoid correcting these on OES, but Zn, Ni, and V fall at the border of sensitivity. I personally don’t trust it enough to correct those either. The tank will look much better if you take care of the top part alone.

I agree. No need to add sulfate, but do raise the salinity (which will raise sulfur sulfate). That will also fix the low potassium, magnesium, and calcium.
