Rice Reef's 120 SPS Reef Tank

[Rice Reef]

After another 20% water change today I checked the PO4 level with the Hanna...
.23... Almost fainted... Did another test again and the same result...
Then it hit me... I forgot to divide by 1000. Need to convert from ppb to ppm.

So I checked the Hanna po4 checker and it is just the low range checker so it is already measuring at ppm.. My po4 is at .23...

This is after the water change... Will do another check tomorrow... All fish and corals are look fine... Fish are eating... Corals have lots of pe...I wonder if it could be the Zeozym...? Checked my RO water TDS meter reads .000...
Will have to get another test kit to be certain...
