Question on Walmart test kit

[no1ford]

Thanks and to think all this time I thought my chlorine was high enough! No wonder I was having problems.

I may seem super dense although I cannot figure out the bleach calc. It is in litres! I have an 18 x 48 pool with a cya of 30. I just dump an educated guess in every night! It would be great to actually have an exact amount. Can anyone help?

In the upper left corner , click on More Calcs , go to settings , you can put in the values for pool volume and bleach stength , click imperial (u.s. gallons) , save & close..
