Any decent plants like Amazon Swords and Cabomba will help to suck up nutrients like Nitrates and Phosphates.
Its a balance and control rather than eradicate algae.
Cleaning the glass and doing water changes(same time) once a week 10-15% of volume will get rid of any floating algae when cleaning.
Scrubbing ornaments and gravel will help.
Keeping food waste down (No over feeding) will help and general cleaning of the tank TBF.
Some No No's is direct sunlight more than 12 hours of natural light will increase the growth, also if you use of Algae killers can kill plants also and kill off biological filter bacteria!
if you have decent amount of plants they eventually take control and suck up or starve the Algae of what it needs.
