Hair Algae Light Times

[dorecs]

Hi,
I dose liquid CO2 and liquid fertilizer and have my lights on 1pm-10pm.
I'm starting to see green hair algae creep over the leaves of my plant and the gravel,
Will reducing the light time help get rid of this?
How long should I have the light on?
Thanks,
Tom

I have my lights on between 5-7 hrs a day. I have hair algae also. I've started double dosing my liquid co2 and ferts to see if it helps.

hi Tom I've reduced my photoperiod from 8½ to 6½ hrs in split sessions (for my benefit) and my algae problem has virtually disappeared.
As I understand it the more light there is the more the plants are actively photosynthesising and using up carbon and other nutrients. So reducing the time your lights are on will help tho I guess that would depend on what planting you've got.

Hi, My tank isn't too heavily planted , an Amazon sword and a small baby dwarf tears (which is meant to be carpeting the tank but is now carpeted by a layer of hair algae -.-)
I'll try reducing my light time for 2 weeks by 3hrs and see what happens

Fingers crossed!
