Stupid question but, how long for a tank to cycle.
This may be a stupid question but anyway.......
How long does it normally take for a tank to complete the cycle?
My tank is 3 weeks old and I could resist adding some fish early.
It is a 450GL fully planted with huge size sump loaded with bio-ball and fiber mats.
There is already 100 small tetras.
I just lost 2 more fish last night and wondering if it is because the tank is not fully cycled. Most of the fish appear well and the water seemed to be clear.
I have no NH3 test at hand but NO2 was 0.2 and NO3 was 5 ppm last week.
