Default Re: lethargic corydoras

I spoke too soon. The original cory I placed to test it after the first 3 deaths is still alive. however a bn pleco and one corydora are still just hanging in. I did a 95% water change. There is a strong wood odor from above the tank. I believe the soil I'm using has a lot of wood matter. Could the water be too strong in tannins?
