It would actually help if you could post a complete set of current water testing results.

I would shock it up to around 12 with bleach. Once your pool is clear, you can use some trichlor pucks for awhile since your cya is low but keep an eye on it. It can quickly get too high if you don't. But, pucks aren't going to help you clear the pool. It will not take the cl high enough. Save them for after you clear the green.
