Well that does suck. I get some green algae on my discus tank glass so I am trying out a new idea. I have a bunch of floating plants and I plan on making a channel around the perimeter of the tank.
I like the floating plants but they get overgrown quickly. I am hoping this helps keeps them in check and keeps some light off the glass...I have no green algae on my glass where its shaded by the floating plants.
I think the green algae on glass is caused by intense or long light. I dont dose my discus tank at all. I am changing water and with the forest of floating plants its low on nutrients.
Oh yeah decreasing the photoperiod in my 75g put a considerable dent in the growth rate of algae on the glass. There no shading that tank...
