A reflector can be formed outta just an aluminum pie plate....according to what part of the planet you are on, a ph meter can be important...those who happen to be over good aquafers or on (good) well water would only need to check water occassionally...like me...I use well water from a deep well ....ph runs 6.5-6.8 alwasys so I seldom check....of course that is not the norm for most.
