Rated 4 out of 5 by seachipmunk great filter
I got my filter and it was very easy to set up and install. It was pretty loud at first but I took the impeller out and rinsed it off and put it back in and now I can barely hear it running. My water is very clean and clear and it seems to be doing a great job. Overall a very good filter

It does the job of filtering ok for an HOB however I had to heavily modify this thing to make it quiet. This is the most noisy HOB I have ever used in terms of water noise. The design is deeply flawed. There are water chanel s on either side of the intake tube that make excessively loud water trickling sounds. I can hear it over my tv and it keeps me up at night. After I finaly figured out what was making all the water noise I had to stuff filter pad over the chanel and finally all I can hear is a light hum of the pump. So ad often as I have to do water and filter changes I will have to redo the filter mufflers and will be sure to tire of it quickly just to keep this thing quiet, I'll be sure to get sick of it and either go with a Fluval canister or Fluval HOB. I will never reccomend this filter or ever buy another one again.

Rated 1 out of 5 by Ryu100 Never lasted longer than a month
Tried the Penguin 100 on my 20L tank. First one never worked, second lasted about a month and then proceeded to just stop working and my third try gave out on me in about two weeks. While the filtration when working was excellent, I have never had so much of an issue with my filter's lifespan. I spoke with others on a facebook group I am in and the majority had experienced the same issue.

Rated 3 out of 5 by LugNut comparatively noisy, works pretty well in a different room with closed door.
I bought a used 300 when I returned to aquariums from outdoor ponds. The biowheels were missing and the impeller shaft was quite worn and allowed the magnet spindle to bang around, but it was dirt cheap and worked well enough in conjunction with the under gravel system to keep the tank clean. When I decided to set up a second tank I bought a 200 and a 100. Both have covers that ratled from day one. The front covers over the wheels barely hang on and are frequently jostled off their mount points. Still, they also a decent job of keeping the tanks clean and the ammonia in check. After a few months it dawned on me that they were getting louder and I was hearing that mag spindle banging around in both. Sure enough both stainless shafts were worn, and it isn't due to gravel. Both tanks have 1/4 to 3/8 gravel, washed and sieved so that isn't getting in the moving parts on either pump.
I've now switched to under tank cannisters.
