I set up QT again the other day. Attempting for a quick cycle, I rinsed out the sponge from the 20H and poured all the mulm into here. Added some anubias from the 45, some random stones and plant trimmings and a good handful of malaysian trumpet snails. Feeding one fourth of an algae wafer daily, doing tests. So far no ammonia but the nitrite started to spike today. I did rescaping on the angel tank and put discarded stones in here as well, hoping that will boost the good bacteria level. Crossing my fingers to be able to acquire more black skirt tetras tuesday or at the latest, next weekend.
