Lighting and algae?

[Slyguy00]

So about a month ago I bought a maxspect razor led for my tank. Since then i have been on an ever going battle with some kind of brownish stringy algae that is beginning to destroy my tank. It is only on for 8 hours a day and 3 hours just blue. It ramps up from 10:30 and for 2 hours of the day i have blues at 80% and whites at 70% and then it goes back down. I have the light about 2 ft from my water, I syphon my sand, iv tried doing many water changes, iv tested my water and everything seems ok. But this stupid brown **** just keeps coming back, more and more. It also appears that there are little bubbles in with this algae. I tried chemiclean and it didn't do anything. If anything it appears worse. Im just about ready to start piecing this tank out if I can't beat this. So if anybody out there can suggest or tell me whats up id really appreciate it. Because I'm gonna lose my mind dealing with this stupid tank. Thanks again.
