You need to find out the source whats causing is correct.
I always find adding a fast growing plant like Water Sprite helps alot as
well.As it removes excess nutients from the water column.

Algae are not limited by excess nutrients in a planted tank's water
column, except in terms of NH4. There is a 3 way fight/competition for
this form of N by plants, bacteria and algae.

You can add everything else BUT NH4 and never get any GW to induce a
bloom. Even at high levels of NO3 and PO4, I was still unable to
produce GW for many year. It was only after NH4 dosing did it occur.

Anything that causes the NH4 level to rise and reduces it's rate of
uptake allows a chance for it to build up enough to induce a GW bloom.
New tanks with lots of light often have this occur due to, folks doing
fishless cycling with NH4, poor plant growth and poor bacterial
cycling, adding mulm and taking care of of plant needs and not adding
NH4.

As sugested: Water sprite (floating)is especially great since it
blocks the light and is a super fast grower and able to remove NH4
quickly, floating it has plenty of light and CO2, one of my fvorite
plants for new tanks but not needed really if you use mulm and add
enough CO2 and plant biomass from the start up.
