The chlorine may have been irritating her skin because you may have been using unstabilized chlorine (sodium hypochlorite or Cal-Hypo) without any Cyanuric Acid (CYA) in the water, possibly because you thought that as an indoor pool it didn't need any CYA. However, without CYA in the water, the active chlorine level will be much higher. Even 1-2 ppm Free Chlorine (FC) with no CYA is 10-20 times more powerful and potentially irritating than 3 ppm FC with 30 ppm CYA where this latter amount is more than sufficient to prevent algae growth.

The Palintest SP 315C has the same tests as the Taylor K-2005 except possibly no acid/base demand test and is a decent alternative for those who can't get Taylor kits overseas. It uses tablets for most tests, but uses DPD for FC and CC and tests for TA and CH via count the drop tests (I think) and tests for CYA with a turbidimetric test. However, Amanda mentioned a "photometer" so this sounds completely colorimetric for all tests (well, still turbidimetric for CYA). I'm sure waterbear is familiar with these.
