Just saw your post, sorry for the late replies. The green water is caused by excess nutrients (nitrates) in the water column and excessive light. I would recommend you keep the lights off, if you haven't already turned them off, and let the algae die off. Is there any fish in the tank? If so you might want to consider adding an airstone if there are a lot of fish. Green water can suffocate fish at night when the algae uses up O2.
I'm not sure what caused the stall. What did you use to seed the tank? A filter, gravel, or decor? What are your readings now? It has been three days, any changes?
