Bulk Color Changing DI Resin (fills One 10" Cartridge),
is the only product info I have. The product info i receive is non specific. I could ask the supplier for more info if they have it. But I can tell you its the same DI Resin available from some other aquarium suppliers.

What grade is it if I remember correctly there are a few grades (something for water softeners, medical, nuclear)[/QUOTE]
