Sprint chemicals - fixer with hardener?

Hi everybody! I decided to try the Sprint line of chemicals. I already had Kodak Indicator Stop and Photo-flo and Sprint's HCA. I went and bought Sprint's film developer and fixer. When I got home I read the fixer bottle and it said to add their Alum Hardener to the fixer. (It said I need it for negs but not for prints.) Do I really need a hardening agent in my fixer for my negs? I'm developing mostly Tri-X and some T-MAX.

Thanks in advance,
