Rock is green when lights go out

Ejb · 10/09/2017, 10:23 PM

During the day I have no algae on my rock but when lights go out its all tinted green where the light would hit. Is this bacteria on the rock? I would like to think its a start of coraline algae but I think that would be a long shot.

This is what it looks like with lights off

I have something similar going on with some of my rock. Stuff bought live when we started the aquarium back when.

The other stuff, dry rock or caribsea life rock does not exhibit the same green hue.

It is algae. The lights change the color so it doesn't show as much. It will probably continue to darken. Natural progression I think.

What type of algae would it be? It doesnt rub off at all, does coralline algae start off as green?

I'm sorry to tell you, but that's radioactive rock. Fukushima did it.

Looks like this during the day

Can you turn off the blues and have only white light? If you can, I'm sure you'll see it as you do at night. It's always there, the blues just hide it.

I unfortunately dont think I can, its a kessil a360

Hi have you figured out what type of algae that is? I have had the same issue for about 6 months. I don't have any green hair algae. When the lights are on the tank looks pretty decent but with the white lights or when the lights are off it makes the tank look really ugly. smh... I tried Rowaphos, chiller to bring temp down, lowered lights, chaeto to compete with algae, uv sterilizer... Whatever it is I think it's messing with my coral growth as well. Was thinking it was the phosphates but my hannah checker is reading .00 It can be that my rocks or sand are leeching phosphates.
