I'm currently using a Taylor kit (K-1720; 20-100ppm range). It uses a 15ml water sample size and requires 15ml of reagent (R-0013) for each test.

I noticed that Taylor now has a kit (K-1721; 30-100ppm range) that uses a 7ml water sample and requires 7ml of the same reagent (also R-0013).

I'm thinking of replacing my old kit with the new one since it will save me money on reagent (I've had to use more this year due to lots of heavy rain).

Which brings me to my question; are both kits equally accurate or is one more accurate than the other?

Thanks.
