I was trying to use the follow script to tweak the recipe a bit
mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:ammonia>, <liquid:ammonia>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:sulfuric_acid>, <liquid:sulfuric_acid>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:oxygen_difluoride>, <liquid:oxygen_difluoride>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:sulfur_trioxide>, <liquid:fluorine>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:hydrofluoric_acid>, <liquid:fluorine>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:oxygen>, <liquid:hydrofluoric_acid>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:potassium_hydroxide_solution>, <liquid:hydrofluoric_acid>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:sodium_hydroxide_solution>, <liquid:hydrofluoric_acid>); mods.nuclearcraft.chemical_reactor.removeRecipeWithOutput(<liquid:hydrofluoric_acid>, <liquid:calcium_sulfate_solution>);

However in ct log it shows that it has errored

Ok seems that I need to add the amount of fluid then, this can be a bit confusing...

Looks like I need to fix the logging, but yeh, fluid stacks are like item stacks and need the size of the stack also... perhaps I could add a boolean to not check stack sizes.
