Hi, Ellen. Sorry nobody got back to you quickly after your last post.

How is it looking now? It has been a couple of days, so can you give us new chlorine and pH numbers? No need to test the other things right now. If your chlorine is really high, use the color chart here to try and interpret the level:> http://pool9.net/oto-chart/

Don't add any more algaecide. Those don't usually help and can often cause issues. In fact, for now don't add anything else to the pool other than chlorine and preferably bleach instead of other forms of chlorine. What kind of shock have you been using? Give ingredients.

(You can ignore the bromine column on the tester.)
