Very High Nitrates and phosphate

[biom]

thank you
I have the reflector because of the light spill, the tank in my lounge and the spillage is really annoying.
I will say I don't have a lot of algae, just hair algae here & there and not a lot or even rampant or even in the brightest areas, do you think I could max up the light to 80-90%?.
Thanks Again

Imo you can max it up to 100% but not with the 55 reflector. it will burn the corals from that height (9”) . You can use some of this 3D printed shades if light spills is not acceptable.
