running t5 lights and algea

[matix]

currently running t5 lights 2 10000k light cycle from 11am to 9pm and 2 purple blue antinics these go on a light cycle from 10am to 10pm

issue is my tank is growing dark green hair algea.

some other considerations that may help,

if i were to change the antinic blue purple cycle to ber 10am to 11am and 9pm to 10pm would this stop the algea from growing.

I am currently running a coral life 65 skimmer, which needs up grading but its running and water changes are done on avereage of 5 gals every week. or a 65gal tank.




fish are feed normal

and phosphate is near 0

any suggestions or comments?
