It looks like standard Taylor test chems with the older numbering scheme can be substituted as refills.

For example, if the CYA test is equal amounts of pool water and re-agent, then Taylor #0013 should be the same re-agent as Ben's #1.

In the T/A test, Re-Agents #1, #2 and #3 sound EXACTLY like Taylor re-agents #0007, #0008, and #0009.

In the CH test, Re-Agents #1-#3 sound like Taylor #0010, 0011, and 0012.

In the pH test, 0014 is the same number as the Taylor re-agent 0014 (Be VERY careful--0004 is NOT the same reagent).

I can't quite remember the numbers for the FC test..Maybe I'll add them in later.

I suspect the OTO quick test is just the standard OTO re-agent available anywhere.

Somebody with the PS-234 should test these Taylors against the PoolSolutions and see if the results are the same.
