I am ordering a K-2006, is there any additional reagent I should order at the same time,

I recommend that you get one each of the following extra reagents:

R-0870-I DPD Powder, 10 grams

R-0871-C FAS-DPD Titrating reagent, 2 ounce bottle.

R-0013-C Cyanuric acid reagent, 2 ounce bottle.

R-0004-A PH indicator solution 0.75 ounce bottle

Be aware that the R-0871 reagent is the one with the shortest shelf life. If it turns pinkish or orangish in color it's gone bad and needs to be tossed out. DPD powder is good as long as it has not turned black or clumped together. Having too much on hand can also be unwise. How much you need really depends on how stable your water is. pH reagent can go bad after a few years. When it does it seems to read around 7.6 even when the pH is far from that. Unless you are testing a LOT of pools or spas it is often better to order smaller quantities of these reagents and replace them more frequently. The Cyanuric acid reagent has a long shelf life and is not a problem.

The points about shelf life are good to remember. I think that the R-0871 should last about 12 to 18 months under good conditions.

I like to have extra reagent to avoid running out. If one has a high cyanuric acid level or algae or both, then they can use up a lot of reagent in a short time.

Also, the reagent is not typically available locally, and must be ordered. It can take up to a week to get the reagent, and there is the extra shipping cost.

I also find that people will test more frequently if they are not concerned about running out of reagent.
