Lights and algae

Good morning, just wanted to ask (yet) another question if that's OK?
I have considerable green algae on my rocks, the back wall green algae is slowly turning red don't know why. My lawnmower blenny doesn't seem to like my green algae, seems far happier stripping the nice purple stuff off my rocks.
Anyway, my question is about my lights. If I reduce to 8 hours a day, from 10 they are on now will it improve my green algae? I don't see two hours making that much of a difference. I'm on holiday next week so am thinking of setting a timer to come on at 8 am off at 1600. After 1700 my living room is normally in full daylight as the sun is that side of the house so the tank gets some daylight then. I try to limit it but mot a lot I can do unless I live in darkness.
I have some soft corals, will they be OK on 8 hours a day lights?
My current schedule is led on at 7am, t5s on at 8am, t5s off at 1600, leds off at 1700, blue led strip on at 1900 until bed around 2200.

My lights are
interpet t5 36w daylight 50/50
Interpet t5 36w daylight reef
Interpet reef daylight led strip
Interpet twilight blue led strip.

All the lights are as the tank came, I don't have the electronic skills to upgrade myself. So the hood is as sold.
When on a timer it's either all on or all off as they all work off the same plug, so there won't be a blue period when I'm away.

My phosphate level is 0.5 which although not ideal, is not catastrophic. Same for nitrate level around 20ppm.
My tank is still new @8weeks so I'm hoping it will settle down more as time goes on. Overall I'm happy with how 8 weeks has gone, corals are growing and multiplying, most of my cuc are alive (think I lost 1 turbo snail). My one fish a lawnmower blenny is getting used to tank more every day.
Just wondered about the time I should have the lights on for without it being detrimental to the corals.

I have to thank everyone who has helped me these last few weeks. The advice from this forum has been invaluable.

Pics are the 3 lights
Pic 1 leds only
Pic 2 leds and t5 (as recommended by kent marine)
Pic 3 blue led for night viewing.

8 hours is fine..
Algae is normal with your new tank..
Keep working to reduce nitrates and phosphate levels..
