I recently started a pico reef tank ~2 gallons in a cookie jar. I added BIO-spira and dosed with Fritz ammonium chloride for the cycle. I continued until the tank was able to convert ~1-2 ppm ammonia into nitrate within 24 hours. I did a 90% water change to remove the nitrates, and tested the tank a day later:
34.8 PPT
78.0 temp
Ammonia 0 ppm
Nitrite 0 ppm
Nitrate 1 ppm
Phosphorus > 200 ppb (> 0.613 ppm phosphate)
Calcium 421 ppm
Alkalinity 8.6 dKH
I'm confused on where this phosphorus is coming from. I'm using Tropic Marin Pro-Reef salt (freshly mixed at 35.9 PPT gave 8.8 dKH, 436 Ca, and 24 ppb phosphorus), and about 2 pounds of formerly live rock that was cured in RODI water. RODI water remains at 0 TDS. Any ideas? Other than the phosphorus am I ready to add a few coral?
