    A sponge will probably NOT clear your cloudy water as the pores are to large to collect the microscopic particles .
    However if you turn the flow rate to a bare minimum the particulars should settle out in a day or so.
    Then a good vacuuming will remove them with a water change.
    I use a diatom filter (with no shrimp in the tank ) when setting up a new tank if I use sand or ADA type soils.
    removes the dust with in a few hours.

    As a Bio filter yes.
    Microscopic organisms will grow and attach to the structure of the sponge filter.
    Then the bacteria will consume other bacteria/chemicals in the water.
    But unless you have an extremely small pore size the filter is just not capable of filtering out very small microscopic
    particles.
    That is why we use HOB filters with floss or canister filters as the floss will accumulate the particles thus cleaning the water.
    A diatom is just the fastest way .
    A sponge will accumulate organics and other stuff over time but again it takes a lot longer to clear up and if you agitate the gravel you will find that a lot of the stuff has just settled out and not actually been caught by the filter.
    Again we where talking about CLOUDY water not bacteria. They are not necessarily the same thing .

    it is normal to have cloudy water in newly set up tanks, sponge filter requires time to build bacteria, you can try canister filter, or i think lfs carries like drips that clear cloudy water.

    I have a few tanks with sponge filters. Not only they work great as a bio, but the water is clear too. And they are easy to clean and the water temparature is lower in the summer than the tanks with a internal filters because of the air flow. I like this type of filter a lot. Not to mention they are cheap as well.

    I think sponge filters are the best if you put the correct amount of air through them.

    How can you tell if the amount of air is optimal. I have seen when I put too much air through they start to chug. Just a little less than that?
