Do I need to use this in my fixer?

 

No. If you want to ferrotype fiber prints, it will be very helpful; it also increases the glossiness of glossy RC paper. The downside is that hardened emulsion is harder to wash, so for archival prints (particularly fiber-based), it is not recommended. 

By the way, alum hardening converter is the only Sprint product that should NOT be used with another manufacturer’s chemistry.
