    Do you have a link to the bigger video? Hard to see. Looks like a type of hair algae from the small frame video.

    Is the tank fully cycled? All tanks will go through an algae phase in their life time. If past that, excess nutrients and/or phosphates getting into the tank. Do you use RODI water for top offs and water changes?

    I only took like a 10 sec video or however long it was yes fully cycled and no I live on Hawaii so I get free filtered salt water that the state put in that goes out into the ocean it gets filtered then comes up to a tap

    Looks like diatom bloom. Have you tested the water for nitrates and phosphates?
  7. Jaystank Member Member

    Yes yesterday phosphates were either at 0 or very close to 0 nitrates were at what looked like in between 0-10

    What are you using to test the phosphates? The only way I can get any reading for phosphates is the hanna meter. You want it to be in the .03 to .09 range. I run phosguard 24/7 in a reactor in my sump to keep phosphates and silicates low. Live rock handles the nitrates.

    When the phosphates start creeping back up I replace the phosguard. Lots of folks use rowaphos instead to achieve the same results, low phosphates.

    A turbo snail would help control it too.. How big is your tank?
