You can use a dilution method to force your kit to read higher. Not super accurate, but better than nothing while you wait on your good kit to arrive.

Testing Without a Good Kit

Test the chlorine this evening (when the sun is off the pool) using the dilution method. Then, add enough bleach to get back to a chlorine level of 15-18 as Janet mentioned above. An hour later, retest your chlorine again using dilution. Tomorrow morning within 2 hours of sunrise, test it again. Report back with how much chlorine you lost overnight. Try and keep the chlorine level at 15-18. The more consistently you can do this, the quicker you can clear up the pool.

Run the pump 24/7 and clean the filter as needed.

All your other readings look fine. I don't think you need to drain. If you can keep the chlorine level high enough and be consistent in doing so, you should be able to clear it.

EDIT --- looks like Janet was posting while I was typing but as you can see, our advice is similar.
