So I have a 75 gallon mixed reef which was started in February. I've used Salifert tests kits since the beginning and have never read phosphate or Nitrate above zero.
Long story short, have been feeding like crazy (mysis, reefroids, phyto), turned the skimmer off, removed the filter sock, cut down on refugium lighting...still zero. Started dosing Tropic Marin Plus-NP at max dosage (3mL per day) for weeks, still zero.
I just received a Hannah phosphorus checker, and even it read zero!
So I took 1 Liter of RO water and added 1 mL of Plus-NP and the checker shows 32ppb [0.098ppm phosphate].
Would it be an absolutely terrible idea to do a single or several large doses in order to raise phosphate to 0.03ppm?
If my math is right, I have 90 gallons [341 Liter] of water then 1mL/L * 341L / 3.333 = 102mL should give me 0.03ppm.
Thoughts? Is this crazy? I'm getting desperate as my acros are starting to show significant stress and I believe it's due to lack of nutrients.
