Put sensors in 3 of them 6 months ago -- water temp, pH, DO, salinity. Also have 2 years of production records for all 8 ponds. > > Problem: data is in two separate systems and I can't connect them. I want to know if the water quality data explains why some harvests are better. > > Can you help? I have the CSVs. My friend said something about SQL. I just want to understand my ponds better. > > Can talk this week except Thursday -- harvest day.
