So I've had problems with high nitrates for awhile now. I just started dosing with nopox. Those that have used this before, how long until i notice a drop in the nitrates? Will it effect the corals or fish and when i stop using it do i slowly reduce it? I'm dosing 2ml a day in my waterbox 20. i have several torches that just wont open, but my hammers are doing fine. Any thoughts??
