Don't add anything thing else right now but bleach. No clarifier, no other pool store goop. With a CYA of 85-90 or even 100, I'd suggest shocking up to 20-25ppm. Each time you test, add enough bleach to get back to 20-25ppm. No such thing as testing and shocking too often when you are trying to clear a pool. You should also be running your pump 24/7 and cleaning the filter as needed.

Regarding the CYA test --- you read it when the black dot completely disappears. It definitely is the hardest test to read.

Until your kit comes, you can use a dilution method to force your kit to go higher. You will need to buy a jug of distilled water to use to dilute your water sample with. More info about it can be found here: Testing Without a Good Kit

Hope this helps!
