If the Culator is turning color, then it looks like it's working--please, before you get rid of it, take pictures--both of the outside and inside. We're still researching this to make sure it does everything it claims to, and all the documentation we can get helps! If you can take pics, send them to poolforum@gmail.com, and reference this thread, or at least your username.

Thanks!
