I can’t really help on those lights but at the depth I’d say you will need good lights which then really leads into have CO2 and a ferts dosing program.
I’d get the CO2 going (along with a drop checker and good flow to push the water around) as soon as possible.
Pick up a dry ferts package and keep phosphate above 1ppm. This may help with green algae (jury is still out).
Liquid carbon will definitely help with any black beard algae.
Algae loving fish also help.
Then with CO2 and ferts not the limiting factor, lower lights to 6 hours and then work back up. Aiming to get good sideways growth at substrate (or plants at least growing) but not too much algae.
On my tank I run lights 7.5 hours, it was 2.5ft deep but I had 4 inches of substrate and I ran an LED light and quad t5ho.
With the leds - run white / red lights at 100%, run blue lights less. This is because red light doesn’t travel through water well so you need lots of it for the plants. Blue light does so not so much needed.
Generally allow some weeks to months to sort out.
