Slowly upping my dosing....the PO4 is at 1 so thats fine now - just need to figure out how much is used to keep it there.
but NO3 is still reading 0...even allowing for an iffy test kit its still low (the water remains crystal clear in the tube- i added some nitatre from my dosing and it went pink so the kit does work!)
So far i have built up to adding 3ppm a day...been on that for a few days and was on 2ppm for 5 days before that - 1ppm 5 days before that.
Could i still be showing 0 ?
