Good working and cute

The media could not be loaded. use this in a temporary 3 gallon tank for my fish (going to upgrade soon), nothing can beat this filter! I took out the filter that originally came with this TopFin tank and it was horrible. This tank was also used to house betta fry temporarily, and it was very gentle with them and I loved that I could adjust the flow with the valve (you need to buy a separate air pump - I used the tetra brand, and you need to buy a separate check valve & airline tubing.) anyway, it's great. Even the baby betta fry found it gentle enough to eat little micro organisms growing on it. My water has never been this clear before. It was always murky and cloudy and I feel like this filter is magic. I also washed it out before when it collected brown tannins and dirt after using it for a while, and it came out clean as new. I still have the free extra green sponge they gave me when I placed this order, which won't be until a long time I'll use it. Great buy! Would definitely buy again when I upgrade/get a bigger tank.

Tried a couple of internal filters but had no luck keeping my tank cleaned even for the week. No luck with the black internal sponge filter nor small hybrid sponge/biomedia both purchased from AMZ.
I was changing the water every wk. This hobby shouldnt have to be that much work. Decided to browse all over AMZ for a suitable sized filter to try. Finally I think I found a keeper. Ideally I wished it was smaller and less bulky in appearance, but it works so hey. I currently have a jumbo glass container to house shrimps, snails, cories, and endlers. Small bioload overall, but my ramshorns are the biggest problem, leaving cloudy waters within the week (I don't overfeed).
For now, I was surprised to actually get much more visibility into my tank. It is like having an updated TV with higher resolution. My water used to be clear with the old filter methods but overtime, those filters stopped being as effective despite cleaning with every tank maintenance. Hopefully this will stay functional for a long time.
My shrimps been clinging onto the sponge filter ever since I swapped my filter.
Noise - barely noticeable.
Output - depends on your air pump. Mine is non adjustable so outflow is not too strong.
Set up - super easy straightforward. No manual needed.
Sponge is green colored which helps me keep an eye on my shrimps. Would prefer black spronge tho.
Try it for yourself! Good stuff

Beware - this filer only worked for 4 months ! I bought it to use in a 1 gallon tank so it definitely was not being overused . Very disappointed.
I did get ahold of customer service and when I told them what was going on with the filter , they sent one immediately !!
I am very pleased with how they resolved the issue .

Works well and easy to set up
