[amin36]

Hi guys.i have concerns about tds level.should i change the water at a perticular tds number(5000) or should i just controlthe water parameters.would someone please refer me to a thread where tds is well described over there

TDS is not a number that tells you anything. My pool has a very high TDS, because it has a SWCG.

You need the components of the TDS - calcium, CYA, and salinity. Those matter.
