Only fish i have ever heard tds levels and proper care in the same sentence is fw discus.
*I am lying hill stream loaches only fish i have tried and failed to keep.

It it virtually impossible to use tds as a measure of health in sw imo. Chloride and sodium will add to tds.

Agree. If you are using municipal water, I would not worry about quality for a cat shark. If well water, I would just degas it first.

You can use this to test for TDS before you mix the salt.

You want 0 reading before mixing the salt.
