What are you using to test with? Hope it is not test strips; we put no faith in their results. The kit we recommend is the Taylor K-2006 or 2006C (test kit link in my signature below).

If your stabilizer result reads 100, that means it could be anything 100 or greater. You will either need to do a partial drain and refill (never totally drain a pool) or run higher than normal chlorine levels. See the Best Guess Chlorine Chart in my signature. It explains the connection between CYA (stabilizer) and needed chlorine levels.

What are the ingredients in the shock that you used?

Go to Walmart and pick up a bunch of jugs of their generic plain, unscented bleach, an OTO/Phenol Red kit (yellow and red drops) unless you have a drops kit already, a couple of boxes of 20 Mule Team Borax (landry aisle) and a jug of distilled water.

Add a cup of Borax slowly to the skimmer while the pump is running, breaking up any clumps. Then, add 2-1/2 gallons of bleach (Do these things this evening if you can.) You can do the bleach slowly right into the skimmer as well after you add the Borax. You don't have to wait. Run your pump 24/7 while you are trying to clear the water.

What kind of filter do you have?

Repost with the requested information and someone here will try and help you get this cleared up.
