Is the pool still green or only cloudy now? What is the ingredient in "Green to Clean?" I can't imagine that it could cause your CYA to go up from 30 to maybe 100+. Maybe the test result was read incorrectly the first time. Also, retest your chlorine and get a FC and a CC reading for us.

In your pool, each gallon (4 quarts) of 6% bleach will add 2.3ppm of chlorine to the water. Use that to help you determine how much bleach to add each time you test to take the cl back up to 25ppm. Have you done the overnight test? That is where you test the chlorine in the evening after the sun is off the pool and then again within two hours of sunrise to see if you are losing more than 1ppm of chlorine. If you do, then you are still fighting something in the water and need to continue shocking.

I know your family is anxious to swim, but we need to be sure things are safe before recommending that you let them in the pool.

I understand about not wanting to drain. Just run higher than normal chlorine levels after you get this cleared up and you'll be ok with the high CYA. Don't add anything else to the pool right now except for bleach to get to 25. (Except for some Borax if your pH drops any below 7.2.) Test as many times a day as you can and each time get the cl back up to 25. There is no such thing as testing and dosing too often when you are trying to clear a pool. The more times a day that you do so, the faster it will clear up. Run the pump 24/7.

EDIT --Apparently Janet posted while I was typing, but our advice is basically the same.
