Dosing Nitrogen when Nitrates are present
I have a tank that consistently stays at 12.5 to 25 ppm of nitrates...do I need to dose nitrogen?
29g - fully cycled, established
0 ppm ammonia
0 ppm nitrite
12.5 to 25 ppm nitrates
co2 pressurized 2 -3 bps (in the green)
pH 7 (evening after co2)
pH 7.6 (morning before co2)
weekly 50% water changes (r/o - tap mix 2 to 1 ratio respectively)
I dose phosphorous and trace elements. Stopped dosing nitrogen because of consistent 30 ppm nitrate level and fuzz algae, then algae went away when I stopped the dosing.
So, do I need to dose the nitrogen when my nitrates remain a stable level?
