Hello,

Coralline won't grow if you have green algae there.

Hi guys....

I currenly have green algae growing on my back wall(in fact it is covering the total back wall surface)...I currenly keep the side and front glass clean...should the back wall be cleaned alos, or will the coraline take over with time....

Hoping to hear from you on this....
thanks...Marco
