    It most likely is a unicelluar bacteria called diotoms and it eat silicates if you are not adding more via tap water or new substrate it will run out of food and die also how long are your lights on and how new is your tank

    Lights should not be kepted on for more than 7 hours a
    day

    actually increasing the lighting helps to remove diatoms. (brown algae) ...decreasing lighting is what u do if u hav green algae.

    Diatoms usually go away on their own. Nerite snails will also eat them if you want to get those.

    As anders said they normally ho away on their own and are completely normally in a new tank.

    More current, more lightung and more time ate the vedt eays to minimize it.

    i've just finished battling it myself, i moved house and used new sand when i set the tank back up, i think the silica content in the sand caused it. i increased lighting and took all my hardscape out and blasted it off with the hose. hasnt come back since returning items to the tank.

    Aren't diatoms a protist? They are specifically eukaryotic. I don't mean to be overly pedantic, but calling something a bacterium does suggest antibiotic like treatments on the water would work when in reality it would only threaten the bio filter.

    Sorry in saltwater diotoms are photosynthetic as well as eating silicates I guess I haven't had to deal with fresh water diotoms in so long I didn't know

    Thank you that was very helpful. Sorry was on vacation. But I kept the lights off all 5 days and the algae seems to have diminished. Lights were on a 12/12 cycle I’ll change it to 7 hours on tonight.
