no they say the same things because there are different causes to algae problems and there are many ways to fix it, just read and pay attention to things.
what size power heads and what size tank do you have? do you have alot of surface agitation?
in a saltwater aquarium adding a bubbler is never a good thing, you get alot of salt creep which will remove salt from the water. the best way to get air into the water is by aiming a power head at the surface and give the water alot of gas exchange.
