Algaecides can be dangerous to certain fish, plants, and other tank inhabitants, even though the labels generally state otherwise. I imagine it can also be more difficult to judge whether or not your efforts to correct the cause of the algae are working.
I prefer to do a bleach dip for my plants, which I admit also doesn't go well with certain plants (red melon sword for instance), but keeps the fish safe, and works much faster and more effectively than typical algaecides. 1:20 mixture of bleach to water, submerge the plants/decor in the mixture for 3 minutes, soak in dechlorinated water, then return to tank. Anubias and other more hearty leafed plants do very well with this treatment.
But again, the bleach method is a band aid, just like algaecide. I'm still fighting my battles with algae, I just like to have an algae free tank for a couple weeks every once in a while, lol
