I just got an RODI filter and wanted to test it for phosphates. Can you use a saltwater phophate test kit to test rodi water or do you need a freshwater one? Also, what else should you test in the water you make?
 
Looks like the phosphate kits are for fresh and salt water. Also test for PH and salinity...
 
If it's the API test, then yes, it's the same for both fw and sw

I recommend getting a TDS meter to test your RODI water. they're really cheap and it will tell you the total amount of dissolved solids in the water.
