Ok, tests as follows:
NO3: .2ppm
PO4: .07ppm
GFO has been off for 24 hours now.
So, yesterday I dosed 1ppm NO3, the tested levels rose yesterday and had fallen again today. Tough to say the effect its having on PO4 because I've been running GFO and only recently shut it off.
So, 24mL solution (2ppm NO3) dosed today.
