Howard, absolutely do not use ascorbic acid with FG7! It is too acidic and it will render the developer nearly useless. Either find sodium ascorbate or use sodium bicarbonate to reduce the acid value of ascorbic acid.(posted 8118 days ago)I think it takes about 1/2 the amount of sodium bicarbonate to do the trick--1/4g sodium bicarb to 1/2g ascorbic acid. You must first dissolve the bicarbonate, let it sit till the fizzing stops, then add the ascorbic acid. I can't vouch for the success of this method, however. If I were you, I'd go to the healthfood store and get sodium ascorbate.
