Finally eliminated 99% of the algae. Tank looks like this now.
Over the past weeks, I have installed a cylinder CO2, a normal disfusser, and increased CO2 to about 30ppm.
I did not decrease lighting or stop fertilization. Dose some trace in fact at one time when I saw that plants stopped. After dosing trace, plants bubbles like crazy.
All these adjustment did not do much to the algae except stop it from growing. Finally put 10 SAE and over a period of 3-5 days, all algae is gone. Now, SAE is in my another tank, only left 2 in this one.
Now it remains to be seen if tank will sustain and not get algae. It will go through a testing period of 2 weeks without algae returning before I do rescaping and trimming.
