The Taylor K-2206 kit is a good choice if you have a pool that is already well-managed.  It contains all the tests you need to keep your pool sparkling. 

If your pool has some water quality issues, we think the TF-100 makes more sense.  It contains enough reagents to perform many more tests for Chlorine and CYA...........very helpful for getting your pool in balance.

Consult the information below to compare kits.  NOTE - The acid and base demand tests in the Taylor K-2006 are fine tests but seldom used for residential testing.  Most pool owners use a The Pool Calculator for the same results.
