Methods & coverage
Shared dates and matching scales within each parameter. Means use measured samples only. Hourly pH and temperature; four daily alkalinity tests; latest daily calcium, magnesium, nitrate and phosphate. Dashed segments are explicit estimates, with nominal times. Unbounded gaps remain empty. Times are Eastern. Aquaria are shown individually; no pooled replicate statistics are implied.

Each parameter retains its own units. Scales stay fixed as you change the time range.
Mean = average of measured readings at the sampling-guide cadence for this time range. Estimates excluded.

How to read these statistics
Mean is the arithmetic average. Variation is the population standard deviation: how widely the readings spread around that average. Range is the lowest to highest measured value. SD is not uncertainty in the mean.
Statistics use the first measured reading per local hour for temperature and pH, all distinct measured alkalinity tests, and the latest measured test per local day for calcium, magnesium, nitrate and phosphate. Zero is a valid reading. Repeated daylight-saving hours remain distinct.
Estimated values and readings excluded for quality are omitted from every statistic. Days measured shows how many calendar days have at least one measured sample; it does not imply complete hourly coverage. Salinity is maintained at 35 ppt and is not an automated measurement.
