TDS/Salt

TDS/Salt

Total Dissolved Solids (TDS) level. TDS includes salt. We have this named "TDS/Salt" for two reasons:

  1. Many people forget about salt, or do not associate salinity with TDS. It's important to include it for an accurate LSI calculation.
  2. This is also a dosing calculator. So if you need to add salt to your pool, this will tell you how much you need for your pool.

Input your Total Dissolved Solids, including salt, into the calculator. If you do not have a TDS meter, you can estimate TDS by adding salt + calcium + total alkalinity + CYA. But a TDS meter is more accurate.
