I'd like to suggest vinegar dosing. My tank is completely void of nuissance algae. I believe keeping kh stable between 8 and 9 and keeping up with my vinegar dosing has been the biggest help of keeping algae in control. It also helps keep phosphate down. That being said a good skimmer is strongly recommended for dosing and help with nutrient export. I personally use a re-circ skimmer. I also prefer to skim wetter then dryer. Similar to weak coffee. A little darker then tea.
