When selecting parameters, some parameters (i.e. total phosphorus, Silica Total, Silic show no data even though data is visible in sensor detail.

• Parameters not showing data:
  • Silica
  • Silica, Total (mg/l)
  • Secchi Disc Transparency
  • Hardness, Total as CaCO3 (mg/l)
  • Conductivity
  • Ammonia-Nitrogen (ug/l)
  • Ammonium (ug/l)

• Remove from Trends page the parameters that are not on explore page
• Check that Ammonium data points, 
• Silica, Total should be corrected and added to Silica, Dissolved. Info should be in meeting notes (or parsers code).
