Thelma,
The only way to ACCURATELYtest high levels of chlorine is to use the FAS-DPD method. This can be tested with Ben's kit or using the K-1515-A test kit from Taylor ($30.00 with shipping).
Since I didn't discover this site until it was too late, I bought all my test kits from Taylor direct here's the link: http://www.taylortechnologies.com/
I get next day delivery since I'm close.
A less accurate method is what is sometimes referred to as the shot gl*** method, take a shot of pool water and a shot (or 2) of distilled water and mix them then test. Multiply your test results by the total number of shots. THIS WILL GIVE YOU A SWAG (scientific wild @$$ guess) RESULT, but it is better than nothing if you don't have the proper kit.
Good luck on your first closing ---- lots of good advise on this site!!!
