Agree
Starting with enough plants to outcompete algae right from the get go, is important, if algae gets the upper hand right away, a minimum amount of plants are not equip to compete it. The plant to fish ratio must be heavier on the plant side.
And one thing to consider is the difference between true algae, and cyanobacteria (many people confuse them).
Cyanobacteria can make use of any nutrients they have access to, different species of true plants have specific needs
Algae usually feels gritty to the touch, cyanobacteria feels slimy.
I have also used Rid-X to outcompete Cyanobacteria.

Rid-X contains a powdered form of inert probiotic benefial aerobes that compete for nutrients with nuisance algae, and cyanobacteria.
They are made for, and normally added tp septic systems. I get Rid-X from the hardware store.
