light problems

[Ghostface]

HI,
I am changing my old lights with Hagen’s aqua-glo x2 and power-glo x2. The tank looks good but I am getting a lot of brown algae and dark green algae. I found that my lights where on for 13hrs. I changed it back to 10hrs but I still am getting algae. Both sets of lights are 35 watts 18000k. This is my first time using this combo. I was looking at changing one set and replacing it with zoo med tropic sun 30w 5500k or ultra sun 30w 6500k. That's all the store has. Should I try a different combination? Are the lights I am using good enough? Not sure about the difference between 18000k and 6500k? Witch sets of lights are better? Need some help?

There's nothing wrong with the type of lamps you're using. It might help to run one set for 8-10 hours and the other set for an extra light spike for 2-3 hours in the middle, as 4 x 35 watts all day seems pretty intense even for a 40 with CO2. Also, look around on the algae section of this forum to identify what you've got and how to eradicate it.
HTH.

Thanks Rey. I am going to get another timer today. I also made a mistake the lights are 30w not 35w.

Thanks Ghost
