I'm almost giving up....:(

I think my BGA attach very strongly to the pebbles. I guess I have to remove the pebbles as well. Thanks for the info

In that case, I do not think that it is BGA. BGA appears as a film lightly clinging to the surface.

It should be other forms of algae.

BBA is what that would be if attached well to gravel.
CO2 would be the issue then.

-Clear it manually.
-Remove hardware from tank and pour boiling hot water on them. BBA will died.
-Next, scrub and prune all that you can.
-Perform water change 50%.
-Ensure your CO2 level in water, during illumination is 20-30ppm. (Most difficult)
-Ensure water circulation in water is good, in another word......all-round
-Add back the NPK and TE.

Repeat the above-mentioned every week.

Result: Present BBA will be weakened, add malayan shrimps and SAE to eat the remains. Future - BBA will not grow anymore as long as you keep up your CO2 and fertilization routine.

Thanks barmby, I will try it out.

BTW, also came across many using the Excel approach. Keen to try too.
