Dark Cobra, I never thought of using algaefix as a dip. I currently have a huge mass of algae infested java moss that I want to put in a different tank, but I have been afraid of introducing the algae to the tank as well. I am going to have to try the dip in a separate container like you suggest. I was dreading having to throw the whole mess of java moss away.
Use a three day dip at the recommended dose. For 1G water, that's 0.1ml Algaefix. Too small to measure! So dilute and discard some of it. For example, if you have a vial marked at 1ml intervals, mix 1ml Algaefix and 9ml water, shake well, discard (or store) 9ml of the mix, and use the remaining 1ml; which now contains 0.1ml Algaefix.
Please let me know how it works, success or failure.
