Tank is in its 2nd month since cycling. I’ve had very stable water parameters for 6 weeks in a row. The stats below hardly vary every week I test. Decided to add a birds nest. Been in the tank a week and this just happened over night. I have a hammer that isn’t doing well either. What’s going on? My weekly water changes keep parameters pretty darn stable.
