Hi! Any expert on Phosphate out there. I am the guy with the "rained out" tank problem. I've finally obtained the full water test kit and I am determined to find out the "mystery" of my failed tank. Here are my water test results:
Date: 1/12/02 * Time: 7:23 AM
Readings from the Octopus 3000:
pH = 8.32
ORP = 280 mV
Temp = 77.6 F
Water test results from Salifert test kits:
kH/Alk = 9.3 kKH or 3.3 meq/L
Ammonia = 0 ppm
Phosphate = 0.5Where did this came from?
Nitrite = 0 ppm
Nitrate = 1 ppm
Calcium = 340 ppm
As you can see. Phosphate was the only one that truly out of whack! I suspected that my Maxima RO system has failed. So, I repeated the Phosphate test with a sample water from my Maxima RO...and the result is (drum roll, please) - 0 ppm!![]()
As I have posted previously, the salt water was mixed using strictly RO water and Instant Ocean salt. I have used Instant Ocean salt with excellent results before and have no reason to suspect the quality of the salt. The only explanation was the quality of the live rock & live sand was totally destroyed by the rain.
How do I remedy the phosphate problem? How bad is this Phosphate dude?
Regards,

0.5ppm PO4 is nothing to get all worked up about.
As you can see in the enclosed pix. I hardly had any algea bloom. Yet, the Pom pom Xenia are contracting and droopy. The Gorgonias are falling apart. The last coral has completely bleached
