What's the phosphorous one for? That's not the phosphate tester

 

phosphorus ULR (Ultra Low Range) Reads PPB (Parts per Billion) where as the standard reads (PPM) Parts per Million

The phosphorus one reads not only phosphates but what phosphates are made up of giving you a much more precise number closest to 0, does it matter? Not really in most cases as all the titration tests are PPM and have worked just fine as would the Phosphate Checker, but for those who want a down right accurate number vs the standard readout they are used to it being the same price It might be the better option, both of them work just fine.

 

@kev311, mind me asking why you decided to sell these?
