Top Fin® Multi-Stage Internal Filter
VERY QUIET FILTER
I have 3 fish tanks in my bedroom... 8 total in my house.. I have had fish tanks for 20 years now.. So I have tried all kinds of filters. I have had HOB's and Canisters and other types of internal filters from tetra for example..
I bought a Top Fin 2.6g square glass tank and it came with the 10g version of this filter and I was amazed how quiet and yet powerfull the filter... So I later got the 20g version for my 10g bow front that's in my bedroom and wow... super quiet... quieter then any Hand on back filter I have ever used... I also have a 27g hexagon and 44g Pentagon corner tank in my bedroom.. I needed quiet filters.... and so I tried the Top Fin Internal 40 filters... They have a amazing amount of room for bio media for its size.. Much more then any single slot Hang on back filters... Its also quiet powerfull but not so powefull that it blows fish around...
I do recommend though in buying better filters for it.. The spong filter is good but the 40g filter has too big a water bypass and debris flow right around the filter.. Buy some Fluval Water polishing pads and problem solved. My room is near dead silent now, and I have a 20g top fin and 3 40g top fins in my bedroom..
On top of this the spray bars eliminate the need for air stones.. so I turned off my air stone pumps.. and also eliminates the need for power heads.. no more power head noise from pumps...
I would give the 10 and 20g filters an A+ and the 40g filter I would give a B+... only because the 40g has too much of a water bypass from the stock sponges.. but if you buy better pads I would easily give it a A+ the storage area for those ceramic rings I really like... What I do is use fluval water polishing pads for the filtering... then I use the ceramic rings for the bio media.. and I use Seachem purigen in the ceramic ring section to make the water clear.

Worked good for a while.
It was good in my 10g but as my fish got a bit bigger and produced more bio- load, it kept getting clogged. I'd definitely recommend but for small bio-loads unless you want to keep cleaning it out every other day.

It's an okay filter. If you don't have the money for a decent filter and you need one this one will work fine
Easy to Install
Changing the filter sponge can be exhausting

Not for Betta; may be okay for other fish
The current this thing produces is way too strong for a Betta in an 8.5 gallon tank. I used it with and without the spray attachment. The attachment was very noisy and sent a strong spray of water out. Without it, the water gushed out of the nozzle, which was submerged, and I could tell by the motion of my silk plants that the fish was going to be unhappy. He wouldn't go near it. If you need a gentle underwater Betta-friendly filter, I suggest the Tetra Whisper 10i. I'm using that now with much relief and, I hope, long-term success. However, don't discount the Topfin filter's usefulness for other fish; it might be just fine for something other than Betta. My review is based solely on Betta-friendliness. The two filters cost the same at my local store.
