Review: Perfect for a Top Fin 3 gallon. - This filter works perfect for a little Top Fin 3 gallon tank. I have a small tank set up for Corydora fry and needed a decent filter with an intake pipe. The filter that came with the aqaurium was trash, and I did not like it. It pulled from the bottom and kept sucking fry up. The first replacement filter that I got did not have a place for carbon or any type of sponge. This one is seriously perfect. It has a carbon cartridge with a sponge and also a sponge filter for the intake. It helps pre-filter AND keeps from sucking anyone up. The replacement cartridges are not expensive (6 for $9.99 or 12 for $14.99). It is very easy to clean and does not make any splashing sounds. It has a big enough area to add your own media, if needed. The carbon keeps everything circulating to avoid any funky smells. *I just put it in before taking photos, so the tank is not the cleanest.
Review: Solid Filter, Would Recommend - This NICREW filter is pretty decent. It's small and doesn't take up much space in my tank, which I like (I have a betta named Bubbles, she loves it). The filter does its job well enough, keeping the water clean and clear. I haven't had any issues with the flow being too strong or anything, though sometimes I wish it was just a LITTLE stronger, you know? Anyway, it's easy to set up and use. (I accidentally put the sponge in backwards at first, but it still worked fine). It came with everything I needed, so no complaints there. Overall, this filter is great for small tanks like mine. The adjustable flow is a nice feature too, although I don't really mess with it much. And hey, if you need to clean the media, it's super easy and quick to do. You can't beat that! Definitely would recommend this one to anyone looking for a reliable and quiet filter for their small aquarium.

## Questions & Answers

**Q: Does the filter tube extend? Does the water have to be filled to the top to use?**
A: Yes, it includes the additional tube to extend. It will be better to fill filter case completely with water before it starts. Otherwise, it will take some time to pump water up. (Water must at least cover the motor.)

**Q: What if the filter doesn't start or makes a mechanical noise?**
A: Try to turn the impeller by hand. Check to see if something is jammed in the impeller. Rinse impeller and filter to remove blockage.

**Q: After a powerout, will this filter restart on its own?**
A: Yes, the motor will restart by itself once the power turns on.

**Q: Can I use this in a turtle tank?**
A: It is not recommended for turtle tanks.

**Q: Does this filter fit on a framed aquarium?**
A: Yes, you need to gently pull the intake tube to hang on your framed aquarium. The width between intake tube and housing is 0.4 in.

### ⭐⭐⭐⭐ Keep your tank clean and this filtration device works great
*by A***. on January 15, 2026*

I like this filter as it is easy to assemble, it is safe for water not being able to absorb into the electrical box and cause major issues. It’s small and quiet. The filter functions well if you upkeep on your substrate or gravel. Otherwise you will have to clean and scrub this filter weekly (which I do anyways). I am thinking of upgrading to a higher quality filter that isn’t hard to clean and isn’t all plastic, which may be hard to find but in the mean time I am happy with this filter.
