Are low TDS a concern?

[chem geek]

No, not at all. TDS is mostly a measure of the amount of salt in the water. For pools after initial refill, it mostly comes from the calcium and bicarbonate added to saturate the water to prevent plaster degradation. After that, chlorine use increases the sodium chloride salt level.

Thanks; good news for me.
