Ok so green water algae is a single cell organism that can readily adapt to uptake any excess nutrient, be it macros, micros or even traces and requires very little light to survive.
with that all being said a effective method of control is a massive amount of plants and a good deal of fast growing floaters. but with all the plants you must feed them of course, with the fert being added to the tank and the massive amount of plants and floaters they will out compete the algae for the traces macros and micros correct? so once i get enough plants the water will just start to clear up? or will it just slowly go away from w/c to w/c
I disagree with underlined.
Micro algae and cyano actually tank much more light to survive then the slower growing plants.
If you get the plants establaised right from the start you can get them ahead of the algae/cyano.
And adding plants to a tank can make the algae/cyano go away.
But if you do nothing other then kill the lights and stop feeding the algae will die off.
the key is that it will die off faster then the plants.
So when the lights come back on the plants are there to consume the nutrients left by the dead algae/cyano.
And by adjusting lighting and feeding you can keep the plants ahead of the algae/cyano so the tank stays clear.
