Finally got my Nitrates down to 0ppm. Used 80 proof Toska Vodka (Yung Absolut, ako lang umiinom
). Here was my procedure:
Started with 0.4ml / day
increased dosage by 0.5ml weekly
measured Nitrates mid of week
Reached 6.0ml before nitrates dropped to 0ppm
Reduced dosage to 3.0ml for maintenance
Note that I dose 2X per day. 1/2 dose in the morning and 1/2 at night
Got rid of chaeto. No more light in the sump
It has been a week now dosing 3.0 ml per day and nitrates is still at 0ppm
