i never add anything to the BOF, and have excellent results every single time...

matter of fact i have 1 year old chum eggs in the fridge that look, smell, feel, and fish just fine using BOF... it already has sugar and salt in it, no need to add anymore...

if you want a sulfite based cure, use Beau Mac's Pro Glow, or one of the other big brands...

Nates Bait Cure is another one thats in stores now, and a very easy one to use as well...
