Hi 
I upgraded my smallest tank 2 days ago, from 35 litre to 55 litre. I swapped the seeded filter, some pebbles and I have two stockings filled with old gravel in the tank. The ammo and nitrite have both remained at 0 ppm and I'm wondering how long I have to keep these stockings of old gravel in the tank.
There is a betta, 2 panda cories and 2 peppered cories in there.
