Tank is slipping into algae hell - help

[Roskoreef]

I think things are taking a turn for the worse, im loosing this battle and its getting worse.

For a few months ive been battling cyano with no headway, now bubble algae is rampant and Green hair is forming, plus in the frag tank, either brown slime or diatoms grrrr, they are everywhere.

ok so here are my params, lighting etc.

Phosphates -0.04 - hanna
ammonia - 0 - nutrafin
Alk - 128 ppm, 7.16 DKH, 2.56 meq/L
Calc - 476 - hanna
Mag - 1360 - salifert

lighting schedule,

DT-180 gal
8 hrs 30% radion led
8 hrs T5, 372Watts

Frag Tank- 40 gal
10hrs T5, 272Watts

10%/week water change minimum

Im almost certain that there is too much light... how long can corals go without light? enough to kill algae but not corals???

Opinions, ideas??
