red and green algae on sand

[Tremolo]

I have red and green algae growing on the sand. How bad is it and how do I get rid of it?

Thanks Vince

more info needed.....but try increasing water flow, shorter photoperiod and check water for phosphates

well lights are on from 10 to 1030 and i just switched it from 10 to 9 i will see what happens..not much i can do about the flow i have a maxi jet 1200 and if i have it pointed anywhere but the top it blows the sand around. I bought the 1200 because in an old post someone recommened that i install it with a hydor to have better flow...I dont have the hydor on because it pushes the sand around.

Thanks Vince

12.5 hour photoperiod is pretty long......yeah...switch to 9~10 hours...should help.
