    Usually diatom algae occur in newly setup tanks. They go away on their own (in the vast majority of cases).
    Other types of algae usually take advantage of a new tank being out of balance as well so if your tank still isn't balanced after four months, this may be the cause.
    Figuring out amount of light, fertiliser (and CO2 if added) to make sure there aren't a lot of excess nutrients is crucial to avoid the worst algae.

    That pretty much looks as expected from the description.
    How long are the lights on?
    Do you add ferts?
    Water change schedule and tank size?

    Does your tank stand in a bright spot or get any direct sunlight?
    Do you gravel vac the sand?

    It gets dim light from. Tinted kitchen window. But the lights on the tank run later then that into the evening

    Never vacuumed sand

    There's the issue right there. Your CUC is really understocked for that size of tank. I have a 90 gallon and have 30-40 of each and it's barely enough to do the job.
