taylor 5 test kit question

[mcmishka]

I just ordered a taylor 2005 test kit online and I wanted to add extra chemical refills.  Which solution goes the quickest so I can order extra of that or do all get used up about the same time?     Thanxxxxxxxxxxxxxxxxxxx

R-009 is the reagent for Alk  R010 calcium buffer  & R012 calcium reagent these 3 will be used up he fastest

The next will be you ph depending it will be either  R004 or the small bottle R014

Then R001 & R002
