Good morning.
I'm currently SLAMing my pool and this morning I was testing for OCLT and I got 3 different results.
Notes on samples:
Sample 2 = 27ppm
Sample 3 = 25.5ppm
I don't understand how I'm getting such a large range of differences. Is this normal?
I'm currently SLAMing my pool and this morning I was testing for OCLT and I got 3 different results.
Notes on samples:
- Filter pump and cleaner pump had been running all night and were still running.
- All samples were pulled with in 10 min of each other.
- All samples were pulled at the same depth (waterline up to mid bicep)
- 2 month old TFPro kit (so reagents are good)
- Using auto stirrer
- FAS-DPD test with 10ml of water
Sample 2 = 27ppm
Sample 3 = 25.5ppm
