I've been using marine bio wheel filters since mid 90s. A couple of them are still being used today, 300s and 330 filters. I ve had some 350s for over 5 years now. (I have 23 tanks) on 2 i just replaced the impeller. Other than old aquaclear I haven't seen anything last or work as well as these guys.

First off chewy has amazing customer service, I bought this filter March 17, and April 10 it started grinding, I called customer service to see about exchanging it out for a new one, they told me they would have a new one shipped out . I love this filter , I have one in my smaller tank, and it runs like a champ. I think I may have just got one that was funky.

I have been using the penguin 350 and the emperor filter for years. They are the most efficient, durable, and long lasting filters I've ever used. I know some were complaining about noise, but I have found if you lift the intake tube and allow it to suction back down to make sure it's sitting correctly, that will normally quiet it down completely. I do clean them completely every 4-6 months, but for the price you pay, nothing has lasted for 5+ years except for MARINELAND.

I was revamping our 75 gallon aquarium. Decided to try this one, because I can order the replacement filters from Chewy. The price, for the exact same one, was $70 at our local pet store. So I figured double score :)

So I know people are saying this filter is old and has issues. Well so am I. I have used this filter for a long time and will continue to do so. I love the price and I would purchase it again if I needed a filter for a 55 or higher tank. Thanks.

Got this not even two months ago and it worked great at first and now the wheel stopped working and it's not filtering anything... not worth the money.

I have been using aqueon filters for quite a few years with no problems but I had this older one that was beginning to be quite growly and after reading the reviews about both filters I decided that it wasn't just me that I had a growly filter and I ordered my first Marineland filter. I set it up and turned it on and it was like a miracle happened. I didn't realize just how noisy that Aqueon had gotten and the change was most noticeable at night when everything else in the house is shut off

I got the bio-wheel 100, and it’s a very good filter for my 10 gallon female betta tank. At first the current was a bit strong for my betta, but I wedged a bit of aquarium safe foam in the output to slow the flow. It also needed a bit of fiddling around with to get the bio-wheel to spin, and to get the top cover to stop “buzzing”, but now it works just fine. The filter media even has activated carbon and it has the ability to remove discoloration. I recommend this product, but only if you have the ability to do some fiddling around with it.

Can’t get the bio wheel to spin, watched videos, not sure why but the filter system seems to be working just not that wheel
