Question Phosphates from ATI test results

[ConnorA]

Hey, just got my first ATI test results back. I have had some SPS dying back over time that were previous encrusting and thriving. I'm concerned about some of the pollutants in the tank that showed up on the test and have taken steps to fix those issues, but I am wondering if low phosphates can have ill effects on the corals.

Nitrates came in at 1.91 mg/L. I currently dose NoPox, run a small biopellet reactor, and have a decently sized refugium. Should I take the biopellets offline? Should I up my bioload? Should I stop dosing NoPox?

Yes copper zinc and barium are high. Id look for a source of copper. Magnets, metals in and out of tank. Po4 wouldnt really kill the corals in this case.

What did ATI recommend in the report? I use their feedback as a guide mainly but it is usually in the ballpark.

The nitrate has fine, in my opinion, and the phosphate likely is too.
