Hello, I purchased two bottles of Instant Ocean's Bio-Spira and a bottle of your Ammonium Chloride from Dr. Foster and Smith. I followed your instructions of adding one drop for each gallon of water (I have a 38 gallon salt) and recorded my results after 24 hours. I had virtually no ammonia but my nitrite was sky high. I checked again today (48 hours after adding) and having the same results. As you instructed, I have not added anymore ammonium chloride since I'm waiting for the parameters to come down to zero. Is this a normal outcome so far or do you think the Bio-Spira is no longer active? I have documented my build on Nano-Reef.com and here is my link. I have many pictures showing the build: http://www.nano-reef.com/topic/348980-shawnrivs-im-nuvo-38-build-tons-of-pictures/ Thanks.
