Welcome to the forum. I think we can probably help you but a couple of things we will need first:
1. We need current water testing results taken with a drops-based kit (no test strips). It is best if you test your own water rather than relying on a pool store because most pool stores do not always give accurate readings. The kit we recommend is the Taylor K-2006 or 2006C.

2. Please tell us exactly what all you have put in your pool --- ingredients -- not just "shock."

3. Tell us what type and size (volume) your pool is.

4. Don't add any more algaecide or clarifier or anything else right now until you give us some readings to look at.

5. Run your pump 24/7 while you are trying to clear the water. Watch your filter pressure and backwash whenever the pressure rises 8-10 psi over clean filter pressure.

Repost with the needed info and somebody here can help you. Again, welcome!
