So water is crystal clear now, which is good. But big issue cannot drop PO3, at least based on Red Sea test kit. My numbers today:
1. Salinity 1.025
2. PO3 0.08
3. NO3 based on test kit it is negative
can it be a problem for SPS coloration?
4. Ca 450
5. Alk 8.6
6. PH 7.9-8.2 during the day
My pocci still not puffy yet.
