This filter is used in our facility to filter water for rescue turtles in the Rhode Island area. It is always reliable and easy to use with volunteers and interns. We highly recommend it for an easy effective filter.

Rated 5 out of 5 by SoAndSo Good Basic Filtration
The biological insert is better than a sponge, because it's easier to rinse out any detritus that gets caught in it - never needs replacing due to general funkiness, the way a sponge does.
The suction cups are not really strong enough to hold the filter well. Correction: the suction cups are fine, it's the way they attach to the filter by a ridge of rubber that is inadequate. The weight of this filter causes them to pop out.
Otherwise this is a solidly basic internal filter. Good for low-profile tanks without room for an external filtration system. I have two of the 40s, plus an undergravel in my 94 gallon freshwater aquarium, and they seem to be doing the job.
I also like that these filters take the same sized filter cartridges as many of my other filters. The Whisper cartridges are the best, because they aren't sealed up in individualized forms like other brands. You can add any media that you want into the disposable socks and customize your system to fit your needs. Other brands try to force you to purchase their specially shaped, sealed up, filter components. Usually those special components are really just a sock with a different type of media in it. These are also convenient because if you need to medicate, you can put in a sock with no charcoal in it. Other filter cartridges prevent you from removing the charcoal unless you cut them open.

Rated 4 out of 5 by Cupcakesdaddy Works very well
Hi I use these in tank filters and like them because I can put tanks against each other. They take up no outside space. They work well and move water well for smaller tanks. Most of my tanks are right up against the wall and I use plexiglass as tops for my tanks. I clip the filters to the end of tanks. Excellent filters for my purposes.

If you want quiet these are the choice. I found that the 40i often overflowed because it couldn't let out water as fast as it was being pumped in. The small handle that holds it to the tank wall was the conduit dumping the water out the back. The 30i I had previously worked correctly in all aspects. Handles the basics, good for a backup but it takes up a lot of space inside the tank, a canister is needed for 20 gal and up in my opinion for decent filtering.
