Hi All,
After a long absence from having a tank I’ve gotten keen to get back into things and am in the process of setting up my old 6x2x2 again. I’ve shouted myself an Ehiem 2080 Pro 3 1200XL and filled it with the factory pre filter, 4 L of medium grade then fine foam followed by 8 L of matrix. I’ve been working through a fishless cycle and I think its completed but would like to run my data past others. Essentially NO2 spiked to 2-5 ppm nine days ago and has been zero ever since. NO3 has been climbing steadily and is in the hard to read >30 ppm range. I have some lingering low level NH4 but wonder if it is due to the reliability of my test kit at low levels (new in date API freshwater master). Plenty of data below if anyone is keen.
Cheers
Craig
