Melthylene Blue is the common treatment for eggs, however as algenco mentioned, Acriflavin works to... although some are using hydrogen peroxide, or even chlorinated tap water these days with much success.
All I know about the mal. green is that the bottle I have says not to use it on eggs as it will cause them to calcify and is not a suitable preventative in those tanks.
You are certainly free to do what you like...I'm just going by their bottle...However, I'm usually willing to try new things to increase my percentages....
