If your alkalinity only went up to 100, and your ph is low, then I'm not sure that is what turned the water cloudy and green. Do you know what your calcium is? Has the water cleared up at all? I would get the ph above 7, just add borax one cup at a time, testing after 2 hours. In the future you can use Arm and Hammer's washing soda - it will raise both alkalinity and ph at the same time. But for now just use the borax. Post a full set of numbers tomorrow, and we may be able to see what is going on. Sometimes if you have iron or copper in your water, and the ph and alkalinity go up it can react with the chlorine and turn the water green. In this case you would need to add a sequestering agent.
