Welcome back to the forum. Sorry to hear that you are having problems, but we can help you get it fixed.
Can you please post a current set of water testing numbers taken with a drops-based kit (no test strips, please) and let us have a look at them. Also, please tell us what type of pool you have and the volume. We also need to know exactly what all you have put in the pool -- meanining ingredients, not just "shock."
Then somebody here can better advise you.
