    I didn't feel like typing it all out so I made a video.

    The color comes out better on the camera in white light.

    I converted my tank to salt about 3 weeks ago. I have 3 ~2" chromis in a 20 gallon tank. I could use a little help with an algae diagnosis. There is some green algae growing, but its covered in a yellow and/or white crust. It seems an awful lot like lime scale you might find inside an old shower head. Any thoughts?

    I'm at a loss. My scrubber was working really well in fresh water. The only thing I've change is adding salt, and different fish. A month ago, other than having a lot of white in color, the algae was growing and spreading. Now with the same setup it is shrinking and dying. I thought maybe there were no nitrates and phosphates to feed the algae, but my nitrates are really high. (I don't test for phosphates, the what shade of blue guessing game isn't accurate anyway.) I did a 50% water change, and 24 hours later the nitrates were high again. I tried reducing the led lighting, both the intensity and the duration with no effect. I then thought maybe there wasn't enough oxygen getting to the screen, so I added another piece of knitting canvas folded in half to break up the water flow. I even added my old upflow algae scrubber that has no life in it after a week.

    If anyone has any suggestions, I'm all ears.
    (About a 10 days ago I added the chaetomorpha to try and help my tank. It hasn't really grown any either.)

    I have a couple spots of this brown algae growing on my rocks if that helps the diagnosis any.

    You might try adding actual, salt grown turf algae as seed, to start it growing. I left a screen in a creek, all summer in fresh water, I now have a very different algae's growing.

    Looks like basic high-nutrient dark growth. Brush the screen, do 22 hours of light. Strong bulbs would help.
