One more thing...why are you testing calcium instead of using a calibrated TDS meter? TDS meters are cheap.

good call Myka.

Ive seen tds meters at Walmart for like $10

This is highly unlikely to have 50 ppm of calcium at the input of the osmosis unit and then it come out at 800ppm?? where is it coming from? I don't see anything in a standard unit that could leak calcium. ???

Either you have the output and input mixed up or your test is not good.

If you really have 650ppm of calcium in your tank, this is much too high.

Another thought...is the calcium test you're using compatible with freshwater?
