OK, my K-2006 Kit is almost 2 years old, stored mainly inside, except during last summer's short for me pool season (2 months - Aug/Sept). I am in Canada so I am a bit limited to what I can get. I noticed on Amazon.ca that I the Taylor K-2006 is available for $118 and shipping. Do I get a new kit or simply replace certain reagents. If this is the case, which reagents need replacing?
Thanks in advance!
