My experience with this filter so far has been on par with most of the other reviews. I hope I can address some things for anyone thinking about buying this. I have a 55 gallon tank and bought the 350. I dont plan on getting any dirty fish, and considering the movement on this model, I am confident it is enough for the bioload I plan on having. I was leery of getting this over a fluval or aqueon after noise/functionality complaints but if it rates above 4 stars on average it's fair game at that point. It was on sale for about $30 when I ordered it and money talks. Im not an extreme hobbyist or fish wrangler, just a girl who would like a pretty fish tank in her house and has done her homework. So if terms aren't correct or I don't make sense, I apologize. Anyways, To keep it simple, pros and cons: Pros: It is easy to put together. It literally is just common sense linking pieces together and putting in cartridges. It took no more than five minutes. After filling up my tank, and getting it started I was concerned it would be hard to prime. It wasn't. I poured in two cups of water in each side and it was up and spinning. Took about 30 seconds. Max. You put on the little lids which just kind of sit on top of everything without stopping the flow. -The motor IS NOT and SHOULD NOT be loud. I wonder if the people complaining about this followed general fish keeping instructions, let alone the product's. There is a rim at the top of most aquariums, usually black or brown metal/wood. This is where your water level should be regardless of filter. If it is any lower, then there is an amount of space the water has to drop, making more and more noise. The water makes the noise, not the filter. With that said, even the water quickly calms down if people could wait more than 12 hours before writing a review. The instructions clearly tell you to wait at least 24 hours to let the filter break in. The only thing I can hear from roughly 3-4 feet away is trickling water, which is considered white noise and something human beings can naturally block out within a matter of minutes. If I focus on it, yeah duh I can hear it, but it is not enough to tickle me bothered. Its sound, but not unpleasant sound. If you have an aversion to white noise (the sound of thunderstorms, babbling brooks, the sound of the beach) then I suppose this isn't the filter for you. But none of the folks in my house have said "AHH CURSE THAT LOUD FILTER I CANT HEAR THE TV!" -It has room for 4 cartridges at a time. In a sense, that would be great for bigger bioloads without having to get additional filters. Its a nice option. Not one I need right now, but I appreciate the thought. -I cant confirm or deny whether or not it is at 350 gph, but it definitely pushes out enough water to lead me to believe it does. I trust it. Cons: The noise may not be for everyone. I could easily fall asleep with a sound like this in my room. But, I can see why someone couldn't. In my living room it is drowned out. But, if you are all very quiet people who dont make a sound all day, then I suppose you would hear it a lot. We yell and laugh and generally live in our living room thus I could easily be downplaying the sound. -Theres no way to control the flow. I don't need to, but it wouldve been nice at least. -The instructions dont really specify what this one part is. Its a knobule on the intake that moves up and down between vented and covered. I have no clue what it does but would be happy to be enlightened. -This is personal opinion, but its not very nice looking. Ive seen other filters and they dont seem so...intrusive. I appreciate it's size and power but the intake just makes me feel like theres this invasive hand reaching in my tank and gobbling up water. In a 55 gallon there is only one place to put it--in the back corner, next to a heater, tubing, and what I consider the "ugly corner" full of tubing and the heater. Mine is poorly covered with silk plants. In conclusion, its a good filter with some setbacks. I will chalk up any users with mechanical issues being lazy and not cleaning/maintaining it regularly. If you don't want to do that then I say spend the money on something more expensive. It isn't delicate, per se, but I would expect anything in which you are paying a smidge less you could take a whopping 15 minutes every month to clean and check to make sure it is functioning properly instead of whining until the motor burns out from lack of care.

This is my second Marineland Penguin 350 Filter, and I couldnāt be more satisfied with its performance. My first one lasted almost 5 years without a single issue, so when it came time to replace it, I didnāt hesitate to go with the same model again. The reliability and longevity of this filter are impressiveāespecially considering itās running on a saltwater tank. The Penguin 350 has been a workhorse, offering great filtration for both mechanical and biological needs. Iāve found it to be very effective at keeping my aquarium water clear and healthy. The biowheel technology is a standout feature, providing excellent biological filtration that helps maintain a stable, clean environment for my fish and corals. The adjustable flow rate is also a great feature, allowing me to fine-tune the filtration to suit the specific needs of my saltwater setup. I appreciate how easy the filter is to maintain, with quick and hassle-free cartridge changes. Itās relatively quiet compared to other filters Iāve tried, which is a big plus, especially with a tank in a living room. Plus, the filterās durability is top-notch. After almost 5 years of use, my old filter was still running strong with no issues, though I decided to replace it just for peace of mind. If youāre looking for a reliable, long-lasting filter that performs well in both freshwater and saltwater aquariums, I highly recommend the Marineland Penguin 350. Itās a great value for the price, and Iāll definitely be sticking with this model for the foreseeable future.

I used to work as a marine biologist for a major state aquarium. Marineland bio pumps have been around forever. I have been using them for both salt and freshwater tanks in gallon sizes ranging from 10-200. All have worked flawlessly and I will continue to use them as both primary and secondary systems. They are far superior to anything except canister systems BUT in some ways, better than canister filters due to ease of maintenance. I will pick 3-4 of these at one time over a single system any day. Simply, one goes down (breaks), another is still keeping your tank clean and filtered. Please read!!! your fish and you will be much happier and stun everyone else... Advantages: 1) You don't have to shut it down. Pull the cartridge, rinse the new one with distilled water, slowly replace it back in the formed slots. No shutting down valves, seals/o-ring probs etc.. 2) They're pretty quiet but can get the "bubbling noise" when your water level drops below a certain point.Typically just below the flat part of the outlets. It won't hurt it or the fish if it does, it just gets that "noisy" waterfall sound which some, people feel it's soothing. Keeping the water level up is a good thing and remember, those bio wheels add oxygen to the water. Canisters don't. 3) They are easy to fix unless the actual motor goes bad. A wheel sticks? clean the roller pins and slots. 5 minutes. Impeller stops? try pulling and just clean the surfaces of the magnet and cavity; again a 5 minute job. You do have to unplug it for those two jobs. TIPS- A) Do yourself a huge favor and buy an extra set or two of cartridges. They are easily found from mom-n-pop pet stores to large chain stores. You CAN rinse the old ones in an emergency. B) Go to the grocery store and get a gl jug of distilled water and keep it. Reason? tap and even well water has trace elements and minerals that will kill the beneficial bacteria and cause a cloudy white appearance (bacterial bloom) for a cpl days. C) Motor/impeller maintenance - Unplug the pump. Lift the cover off, grab the intake tube (square) and slightly wiggle while pulling upward. Clean with a paper towel and white vinegar on the rubber "grommets" and silver pins you see.Basically, make sure everything that is suppose to spin, does so smoothly. D) Bio wheel sticking - Just lift the cover off. No need to unplug. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. Lightly clean the silver roller pins on the ends. Replace. DO NOT CLEAN OR WASH the paper wheel itself. Sounds like work?? it's not... A canister or in tank filter is ten times more work and messy. These are awesome filters.. Get it and take heed to what I wrote. You'll be happy with it....
