Rated 5 out of 5 by from Very quiet after new impeller Shortly after I bought my filter system, the bio wheel stopped spinning. It would work on and off so I figured I just wasn't cleaning it as frequently as I should or didn't have the water level high enough. But then there was a horrible grinding noise that only got worse after a thorough cleaning. I called the company and the gentleman was happy to help; after a couple questions he decided to send me a new impeller. I received it in just a few days and now the filter is quiet a mouse. I am not only happy with the product but the customer service as well. As a side note, I very much wish that customers would troubleshoot and call the company to get help before leaving such negative reviews. It skews prospective customers' decision making when shopping for a filter system.

Rated 1 out of 5 by from Old ones were great... But these new ones are horrible. Mine bent the impeller shaft after about a month. Looked like the shaft was to long. Was still running, while screaming, until I unplugged it, then it was seized up. I've seen many complaints similar to my experience on different forums. Went and replaced it with an API unit. Couldn't be happier. Step it up marineland.

Rated 2 out of 5 by from 10 Gal Kit - says 100 Filter but actuallly got 75 I purchased this in 2015 and set it up. There is a small BIO Wheel bit it doesn't turn when the lid is on the filter. I have tried to re-position the lid and the wheel, but the only way it does work is when I put something under the lid to hold it up so that the wheel can turn freely. Has anyone else run into this problem? And why does the box say 100 when it is actually a 75? I have had other Bio Wheel Filters (5 Gal) and found they worked fine. I do like the Bio Wheels better than other Bio System Filters, but am wondering whether the 75 was actually tested, or assembled with the correct parts.

Rated 2 out of 5 by from Constant cleaning I bought a Penguin 150 due Marineland's great reputation.Unfortunately I am CONSTANTLY cleaning/replacing filters because they get dirty rather quickly (about 1 filter every 2 days). So dirty that the bio wheel stops spinning, and the water exits out the overflow into my tank. Funny thing is the instructions say to replace the filter every 2-4 weeks. It would be nice if the filters lasted that long. Another issue I have is my small fish are getting stuck on the intake of my pump. It would have been a great idea if Marineland made the intake bigger (like for the Penguin 350). Just a thought.

Rated 1 out of 5 by from Terrible products I bought my marineland penguin 200 a year ago, and one day we were woken up by a loud humming/rubbing noise when we found where the noise came from it was the pump and filter! I shut it off thinking some gunk probably broke lose( not sure how as I cleaned the stupid thing once a month) but the next day I took the thing apart to clean and remove what might be stuck and it was very clean and nothing was stuck!! What it sounds lie is the magnet on the fund is beating against the plastic insides where it sits I paid good money for this thing thinking I had bought a good product nope!!! I have bought Walmart one a few years ago and had to switch back to it and it is still working very quietly these marine land penguin series are terrible products!!

Rated 2 out of 5 by from Waaaaaay Too Loud At first the Bio Wheel was the item making the most noise, a scraping sound similar to when a fountain is low on water. I know it was the Bio Wheel because when I removed the wheel most of the noise stopped. The remaining noise was from the impeller that pumps the water. Over the past few days, the Bio Wheel is making a little less noise but the impeller has gotten louder. I've tried reseating the impeller and making sure the assembly was snug in its seat but it didn't help. The 'splash guard' over the Bio Wheel simply amplifies the noises. My old Penguin didn't make as much noise but somewhere down the line, the engineers or accountants lost sight of the customer's needs. The system does keep the tank clear but the noise can be heard (barely but heard) in the next room.

Rated 2 out of 5 by from Poor power filtering I live in an area where brownouts are common. I am now on my fourth filter in just over a year. It appears not a surge issue since the brand new surge protectors did not trip when the brownout occurred. This would most likely mean there is little to no protection filtering on the power input to the motor, of the pump, allowing for switching transients to damage the electronics. While I have otherwise been pleased with the performance of the filters, please resolve this issue so that I do not have to replace it 2-4 times a year, or look for more durable filter.

Rated 1 out of 5 by from Instantly broken I got the Penguin 350 a month or so ago and it now makes this insanely loud noise when its on and after a few minutes of doing that it just shuts off. I bought this filter because it was affordable for my price range and the reviews were good. I had it running for about 2 days then it started with its loud noise. I think it is the Impeller rubbing but not entirely sure. If there is anything I am doing wrong can you tell me because I set it up like the instructions given with the product and just plugged it in.

Rated 5 out of 5 by from Great filter for the price. I purchased this filter because I found it on amazon for cheap and it had pretty decent reviews. I have to say I'm not disappointed. I originally had it on my 30 gallon tank to over filter due to the amount of stock I had. I ended up upgrading tanks to a 65 gallon still using the same filter. I'm impressed. even though at this point this is putting this close to it's max tank load it is preforming very well. Crystal clear water.My only complaint it that is a little noisier that some hob filters I've used.Great product and I'd definitely recommend it to anyone.

Rated 3 out of 5 by from Was quiet at first... gradually getting louder 350B - was quiet at first... gradually getting louder, but I don't think it's worth the money to replace the impeller for this filter because it doesn't do any better of a job reducing NH3 NO3/NO2 than the much quieter canister filter I have on another tank. It was packed up for about a year and I can't find the bio wheels, which I also think are a bit too expensive considering I don't think they do much. Cartridges are easy to replace but expensive. Flow rate continues to be good. I will continue to use it until I run out of the filter cartridges then maybe sell it for $10. I would consider buying another Marineland filter because many people have had good luck with them, if it is on sale for a deep discount.

Rated 5 out of 5 by from Penguin Bio Wheel 350 I don't normally write reviews, but I felt it necessary to do one on this awesome Product. I purchased one and installed it on my slightly over stocked 20 gal fresh water tank. I did some modifications on the filter. I placed the two 'C' filters on one side of the filter, and in the other side, I put in a foam filter from a different company. On top of the foam, I added a bag of charcoal, and some filter glass wool. The gravel was dirty, so I stirred it up. The combination I used cleared to tank with in 45 minutes. I added some Spira Bio to start the biological filtration since it was a new filter. I checked the Ammonia, Nitrates, and Nitrites after two days. The count for all three were '0'. I am extremely happy with this filter and would recommend it to everyone!! PS..NO NOISE from the filter.

Rated 3 out of 5 by from Penguin 350 Great filter. Easy to maintain BUT, once the impeller begins to rattle, the cost to replace it , including shipping, was $10 less than buying a whole new filter. That did not impress me! Good but disposable I guess. I will compare other brands next time.

Rated 2 out of 5 by from penguin 350 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 from 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 from 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.

1 Fish in my 55 gal tank is sick. Checked water- high nitrite,6.0 acidity. Did 50% water change. (Tap water is 8.0ph , Can t seem to elevate ph above 6.6. Nitrite is at 20ppm. Changed filters out. Added more oxygenation. Should I replace bio wheel?

Asked by: Eqk9
No to replacing the bio wheel. I believe you are referring to nitrate, NO3, not nitrite, NO2. 20 ppm would have killed anything and everything in the tank by now, if it were nitrite. 20 ppm nitrate is okay, no worries. The acidity could be due to your tap water having low alkalinity, so test for this to see if that is the case or not. If the alkalinity of the tap water is low, then your pH can fluctuate a lot. You would want to add some buffers either regularly or naturally, to prevent the acidity from occurring again. Natural slate, tufa or lava work as do aquarium salt (don't use regularly though) or baking soda. If the alkalinity is good, then you need to really think about what is in your tank and driving down the pH. Since nitrates are at 20 ppm presumably, it shouldn't be these. You can add an ion exchange resin to help such as Purigen. BREX

My Emperor 400 filters used to get really dirty, but not anymore. 120 gallon tall tank, running 2 Emperor 400's and a Fluval 405. Same set up was on my last 75 gallon tank and filters needed cleaned every 2 weeks, and changed once a month.

Asked by: Chuck 88
Comparing the two tanks is like comparing apples to oranges. One is obviously a third larger than the other, and therefore, less likely to get dirty. However, how fast tanks or filters become dirty, depends on types and quantities of fish, your frequency of partial water changes, feeding regimen and more. BREX

What are the difference in the penguin and emperor power filters

Asked by: Simba
The Penguin is slightly smaller, slightly less flow rate at 350 gph, whereas the Emperor has 400 gph. The Penguin relies on the water flow through the filter to hit the bio wheels and turn them, so a dirty system will affect this drastically. The Emperor has spray bars that continuously spray water on the bio wheels, constantly turning them. It also has media containers for extra media, unlike the Penguin. It also has a flow manifold housing vs the impeller housing of the Penguin. BREX

If the spray bars are not working, you are missing the flow manifold cover or it is not staying connected or is damaged. It can be found at the bottom of the flow manifold and snaps over the impeller. BREX

Just take the bio wheel out and let it float in the tank for a day or two. Also, make sure the bearings are inserted properly. You can also "grease" them with a thin smear of silicone lubricant. Do not turn the filter off at night, no. BREX

Okay, make sure the water level is all the way to the top of the tank. Fill the filter with water as well. Pull out the intake tube, impeller housing and impeller. Inspect the impeller for damage, build up, gunk, etc. (you didn't state whether it is new or older). If it appears dirty, clean it and clean out the entire filter box. If it is new, and impeller is okay, put everything back together again and re-install the filter. If you cannot get it up and running, call 1-800-322-1266. BREX

I bought a tank and it came with the penguin 200 filter. I don’t know how long the previous owner had it but it seems to not keep the water clean. Would you suggest buying a new one? 

Asked by: Newbie14
No, not if it is running. It may need to be cleaned well if it has a lot of buildup, but it is fine if it is running. New tanks take a while to establish (approximately 6 months), and cloudy water is normal initially. It typically clears up after the first few weeks, but it totally depends on how fast you add fish, how much you feed, and how often you vacuum and perform partial water changes. A clean tank is not completely due to the capability of the filter, the filter simply reduces maintenance for you. Depending on the size of the tank, you should vacuum and change 30% of the water at least twice a month, more often if the tank is heavily stocked or has big fish. If the tank was just set up, you may have a bacterial bloom or an ammonia spike and should add Aquarium Bacteria to the tank. Call 1-800-322-1266 for more help. BREX

I bought and installed the penguin power filter 4 days ago. It's made an on and off again horrible grinding sound. Please help.

Asked by: Adrienne
Do you have sand in the aquarium? If so, this is the issue. Whenever using sand with any HOB filter, you need to place filter floss in the strainer or slide a foam accessory over it to prevent the sand from getting in and destroying the impeller. If you do not have sand in the tank, remove the intake tube, impeller housing, and impeller. Check for any grit from the gravel or carbon dust in the motor or on the impeller. Also, check and make sure the impeller is not damaged, warped, or inserted too far up into the intake tube. Call for more help if necessary - 1-800-322-1266. BREX

Is there a way to lessen the flow rate so it generates less bubbles? 

Asked by: Plii
The power filter does not generate bubbles, unless the water level in the tank is below the filter's spillway. If so, raise the water level. The only way to adjust the flow is to close the mid-level strainer (gray lever). BREX
