Started running BRS bio pellets on 4/20, but did not turn off my GFO at the time. NO3 has consistently stayed at 19-23 ppm for the past 8 months (Hanna ULR) on 400 gallon total volume with heavy bio load. PO4 consistently tests .02-.04 ppm (Hanna ULR). Pellets are in constant tumble in fluidized reactor, with output near skimmer intake (Octopus Regal 300 int). I turned off my GFO about 2 weeks ago, and my question is, will that start over the "~8 week wait time"? I added full amount recommended by BRS, as I see most posts here recommend starting with half the amount, FYI. I also have tested my RO and "nitrate free saltwater" for dilution, both come back at 0.0 on the hanna checker, so I believe the ~20 ppm number is accurate.
