I had a pool service taking care of my pool for the last 2 years & they were letting my pool go green each summer. So I fired them & am trying to figure out how to keep my pool in the blue. It seems very tempermental here in the 100 degree weather of the Phoenix sun. It seems high in chlorine but is still on the green side so we put algaecide in it, but isn't there a way to keep it from going green without going to algaecide? Also I need to buy a good pool test kit so which is better the Taylor 2006 or the TF-100? Thank you.
