    It's okay
  

*by P***G on Reviewed in the United States on July 14, 2023*

The seams are a little... not great. Bubbles escape from most of them. But it seems to still do the job.

     Day two of this little filter. My all-female tank guppy ended up having surprise babies and by the time I recognised they were actual fish and not tadpoles (first time having fish…) I panic-scooped them into my old betta bowl. It got cloudy quick but I don’t want to invest in a large tank until I separate the males from females. I just needed a smallish filter/bubbler and so far this seems to be working.The first pic shows how cloudy the water was the next morning after adding the babies into the betta bowl. Bubble surface in the second image. The bubbles are larger than I expected but they honestly aren’t a problem. In fact, the fry love riding them and playing in them. My cherry shrimpid also much happier. (And oxygenated. I feel horrible.)Third pic shows how much it’s cleared on the second day, though it’s hard to tell since I moved the bowl away from the window. But I can definitely tell a difference.So far so good. Will report back if it doesn’t keep working.P.s. Bought a small air pump and tube meant for a separate small stone bubbler. Just cut the tube in half and added the included check valve (none of which is included with this filter) and it works just fine.

    Mini-Sponge Aquarium Filter...
  

*by L***C on Reviewed in the United States on January 11, 2023*

I purchased this for my three gallon hospital tank. I keep the sponge soaking in my ten gallon aquarium, so that when I need to set up the hospital tank, it can cycle quickly.This little filter works perfectly, when I need to treat my fish for fin rot or other diseases, so that I don't hurt the plants, shrimp, and snails in my tank.My fish recover quickly when given a salt bath in the hospital tank, along with any other treatment they may need when "hospitalized."No complaints at all with this filter.
