I am on the tail end of shocking and am about to run out of 870 drops. I just ordered some but they probably won't be here until Monday at the soonest. What should I do? I probably have enough for 2 or 3 tests based on shaking the bottle.
Should I use pool store tests and save my drops for Sunday? Can I dilute the water and use the standard chlorine test somehow? I am shocking at 19 so it takes quite a few drops to check it. I have been adding around 2 gallons of bleach per day for the last 3 days of the process.
