I read somewhere that salt water is like 23,000 ppm...

TDS is just a measurement of the purity of freshwater. TDS in saltwater is not very meaningfull. I doubt you could even get a reading.

and if you did have a TDS reading no two tanks would be anywhere close to one another. the T in the TDS is total, that means it measures All disolved solids

Ah okay... I feel MUCH better now!
The water is reading 10 before it entered the tank, once mixed with salt it's 750ish.
Sounds good then.

no, 10 is high
out of your ro unit it should be 5-6
out of your di it should be 0
your filters need changing.

Brand new RODI filter...
Shouldn't need changing.
Granted this is what it tested the day I turned it on.
Let me test it now that it has cranked out near 100 gallons.
