does that mean you don't have to buy a RO/DI filter if the water is so clean?

I wouldn't go that far, yes your TDS is low, but as stated above your PO4 is high and you don't want to be putting that in if you can avoid it.

TDS total dissolved solids.
I would venture that phosphate is dissolved in the water and would show up on the TDS meter.

i concur, that is why we have DI (de-mineralization by Ionization) If you measure PO4 in zero TDS water you will not get a reading. That's the whole point of having RO/DI.

Tap water is 17 PPM of TDS here in Port Moody zero after RO/DI.
