CH Test Question

[iwannapool]

Thanks for the suggestion, I will try this to see if it works. It also got me thinking when I went to the link you provided. When my pool was being filled the pool builders assistant accidently put double the amount of algaecide into the water.

Is it possible that this is interferring with my CH testing?

I don't think the algaecide will interfere with the CH test.
