How much peroxide to use

You could add more plants and floating ones, that would help a lot catching all the "energy" flowing down your tank.

Based on the current plantation. It would be low-light for the moment. Yours at 1350 lumen will require a good thick plantation to tilt the balance in favor of plants.

You can also make strips of shades that you disperse in front of the light to cut back on intensity.

Light looks way to bright from the pic. Cut the tops off those ambulia and plant them. Wait 2 weeks and repeat.

Do you mean like strips of electrical tape on the front of the light?

I also have two large limnophila Sessili Flora, one at each end of the tank, out of the photo

Yes, But that will have a tendency to become a gooey mess.

If you have a lid you can try with a piece or strips of light cloth in between. or strips of cardboard.

If you don't have a lid to dispose the shades you will need to get it attached to the light with pvc coated metal wire, for me is the easiest to use.

I remember adding dimmers on aquarium with incandescent lights and they where indeed game changers. Even in these poor conditions.

I've just noticed it says the light has an adjustable light angle, which is basically you can turn the light round to various degrees of brightness, so I have set it, it's now definitely not as bright, I just hope it doesn't effect my plants, anyway thanks to everybody who helped me, its much appreciated.
