: Just make sure if yu order one online from anay place its for SALT and

: called refract. on ebay were sent BRIX type. MOst sold at places like
: Drs. Foster & Smith and Premium Aquatics n Indianapolis, IN, have a
: two year warranty and cost about $40. Yu cna get a fanceier model for
: about $20 more but the results are the same and its not rworth that

: in over 3 years its yet to be off.
