Anything really fast growing, like ludwigia, float some of them to block out some of the light if needed but keep up the photoperiod to 8 - 10 hours. For the green algae, keep up with the fertilisation, once every 3 days with pmdd and a 50% water change once a week to reset it. Keep removing the algae from the glass and anywhere that you see it. Are you doing CO2? If so, your lights might be the limiting factor. Just see how it goes - give it 10 days at least.
