K1005 I-care Test Kit

[BigDave]

The pH comparator in the K-1005 uses a smaller sample (and IMHO is a little harder to read) and reads 6.8 - 8.2 where the K-2006 pH comparator uses a larger sample (more color to see through and compare) and reads 7.0 - 8.0 in finer increments.
I find the "drop 'till the color's gone" FAS-DPD test in the K-2006 FAR eaiser to read than the color match DPD test especially when performing the test for Combined Chlorine. The color match DPD test will bleach out at high chlorine levels; it reads as no chlorine, so, beware. You can add the K-1515 which is the FAS-DPD test - no need to throw out the TA, CYA, CH, pH test 'till they are empty or too old. I haven't used my color-match DPD since I got the FAS-DPD.

Hayward will sell the K-1515 FAS-DPD kit for list at about $20-$25 which has the test vial, 0870 powder, 0871 reagent, and 0003 reagent, plus a nifty box to store it in. Add that to the K-2005 and you have the K2006. The K-1000 OTO test kit from Taylor upgrades the OTO and pH test to the same as the K-2006, and includes R-0014, rather than R-0004 for the pH test. R-0014 includes a chlorine neutralizer so it can read accurately in higher chlorine situations (Chlorine makes pH read high). list on the K-1000 is about $10.

If you have the K-1515 and K-1000, the only other tests you need are the T/A, CYA, and CH tests (acid and base demand are worthless).

Note: Waterbear and I had a discussion on this last recommendation. I have moved every post after this one to the China Shop where it really belongs at both Ben's and 'Bear's suggestion.
Look for Acid and Base Demand.... C.
