Help!
I have cycled for 35 days, 240 liters, dry rock, shimp method, bacter7 and biofuel. Nh3 was 0 2 weeks ago, but NO2 still 5ppm
NO3 was 50ppm, now 18ppm
I run biopellets and rowaphos reactor
Is there any problem??? Because NO2 still 5ppm? Tks for any advices!!!

I'm pretty sure your tank has cycled - especially if there's no ammonia present, nitrates spiked and then dropped. Nitrite testing is only really useful during cycling as you're always going to have some present in your tank.

I personally don’t recommend adding CUC until you have a need for it. Add the first fish or two, then wait and see then when algae, diatoms, Cyano ect.. Appear, add the certain CUC you need to clean that.
