Before going to this site, which I usually do first, I sampled and measured all parameters (with special attention to Reactive P) on the Stoney Creek at the Trentham High Street bridge.
Air temp 24.3 C; Water temp < 20 C; EC 72; pH 6.9; turbidity < 9.
Reactive P 1st reading > 0.25
Reactive P 2nd reading 0.03
Re the P readings, what this seems to say is that I will need in future to clean the test solution tube and cap really well before the first sample (even though I clean this tube after each use) and will need to take two readings if the first reading is high. Of course, the above results also cast doubt on all the previously recorded high P readings.
