"The product itself."

I have had no issues with it being to loud. The Aqua Clear is on the left and the Aqueon is on the right. There must be a huge batch of these units at Amazon right now that are bad. With the 350's inexpensive price point, you can’t go wrong with this powerful filter. Never ever ever use it past a year. I contacted Marineland about my issue and they promptly sent me a new one right away! There is a sound from the water shooting into the tank!

"The product itself."

First they are simple and designed to pump and filter aquarium water. Overall, I'm very happy with this filter. Early on it seems to be working as advertised. This is not my first experience with a marineland filter. I'm a mechanical engineer and understand design. The Aqua Clear is on the left and the Aqueon is on the right. I decided to go with this filter since I had a positive experience previously.

2. Penn-Plax Cascade Hang-on Aquarium Filter with Quad Filtration System

"SAME THING!"

Also the maker should review the pump design. I was using a Tetra in-tank filter previously. I've been researching so many things on how to take care of them. I liked the clean lined look and the pull out basket. I also like the fact that it is relatively low profile and discreet looking. Your fish and you will be much happier and stun everyone else. The filter arrived within 2 days and was the exact same as Petsmart's.

"I was to tire to fix it."

Worst case is that the motor could burn out. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter. Replace activated carbon every 6-8 months ish. DO NOT CLEAN OR WASH the paper wheel itself. I AM IMPRESSED THAT IT WORKS AS IT ACTUALLY SHOULD! I decided to go with this filter since I had a positive experience previously. I was new to the hobby and didn't realize that Tetras were inferior filters.

"A THUMBS UP."

I checked and cleaned it and still just as loud. As for performance, I couldn't ask for a better filter. Now I'm having the same issue with the Aqua Clear 50. You CAN rinse the old ones in an emergency. If that does not work, look into silicone grease so you can lube the impeller. Of course the sound all depends on how much water is in the aquarium. I'd highly recommend not replacing the bio material& sponge, ever.

"Seriously."

The current is strong but you can adjust it with the midsection lever. This new AQ50 filter has loose bio-media, i. SO, I sat down and read EVERY little thing in rhe instructions. I used to have a 37 gallon eclipse aquarium. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER! The lever on the bottom helps even the filter out. This is a good choice if you're tired of cleaning your turtle tank all the time.

"Will UPDATE!"

Basically, make sure everything that is suppose to spin, does so smoothly. It's only rated at 25 gph less, but holds considerably less media. Your fish and you will be much happier and stun everyone else. First they are simple and designed to pump and filter aquarium water. Also price was very reasonable and shipping was fast. Once it loses its charge, you'll need to replace it. I eyedball everything and put it together with a look back at instructions.

"Disappointing."

It wasn't producing much surface agitation. I contacted Marineland about my issue and they promptly sent me a new one right away! I ordered 4 of these, for different tanks of course. I was worried about some of the negative reviews. There is a sound from the water shooting into the tank! The Marineland penguin 350 is a great filter. I put it together, reading instructions of course.

"Not my case!"

I wasn't able to fill my tank fully because there was little to no surface agitation. All in all, I highly recommend this filter and I'm a extremely happy customer! They are easily found from mom-n-pop pet stores to large chain stores. Fill it up with water before you plug it in. I have always used Marineland filters and been happy with them and their quality. I took it apart reassemble it and it's not pumping in the water. My old pump was not working very well so I had to make a major clean up.

"AFTER 3 DAYS."

Works like a dream and can't even hear it! However, lately I've purchased the Aqua Clear 70 and 50. I had a lot of particles in the water. The filter arrived within 2 days and was the exact same as Petsmart's. Unlike my old HOB filter, it doesn't sound like a leaky toilet. Basically, make sure everything that is suppose to spin, does so smoothly. Marineland bio pumps have been around forever.

"+Great price."

Unlike my old HOB filter, it doesn't sound like a leaky toilet. I want to answer some of the complaints I've read. I eyedball everything and put it together with a look back at instructions. If that does not work, look into silicone grease so you can lube the impeller. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. I've looked at so many filters and reviews. They are easily found from mom-n-pop pet stores to large chain stores.

"Will UPDATE!"

My old pump was not working very well so I had to make a major clean up. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter. I used a small pair of pliers and carefully got the pebbles out. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. Basically, make sure everything that is suppose to spin, does so smoothly. They can be very noisy at the impeller, which sometimes quiets in time, but may not. You CAN rinse the old ones in an emergency.

"Came on time."

Overall I would recommend this item. Worst case is that the motor could burn out. I will pick 3-4 of these at one time over a single system any day. All in all, I highly recommend this filter and I'm a extremely happy customer! However, lately I've purchased the Aqua Clear 70 and 50. It's only rated at 25 gph less, but holds considerably less media. I recently upgraded from a 10 gallon aquarium to a 29 gallon.

"Not my case!"

I also like the fact that it is relatively low profile and discreet looking. They are simply the best design for nitrifying bacteria to grow on. I can hear it 3 rooms away grinding away. The first night I had the pump going it started making a screeching sound. I have the topfin 29 gallon tank and used the HOB filter it came with. My tank was a mess when I got this pump. It wasn't producing much surface agitation.

"A THUMBS UP."

Also price was very reasonable and shipping was fast. Really happy with the money I was able to save. Works like a dream and can't even hear it! Lightly clean the silver roller pins on the ends. I will never buy any other HOB no matter what deal they might be offering. Fill up the media slot with water until it's full. The Marineland penguin 350 is a great filter.

"This is the one."

I have contacted customer service to see if I can get a replacement unit. You can't really tell though, and the filter is working great. I've been researching so many things on how to take care of them. My tank was a mess when I got this pump. The filter arrived within 2 days and was the exact same as Petsmart's. Once I found that, the world was right again. Also price was very reasonable and shipping was fast.

"It just starts right up."

That water got so dirty we had to keep changing it every 2 or 3 days. Get it and take heed to what I wrote. I was worried that it might be too much for my aquarium or that it would be loud. I checked and cleaned it and still just as loud. They can be very noisy at the impeller, which sometimes quiets in time, but may not. The filter stopped working all of a sudden. The Aqua Clear is on the left and the Aqueon is on the right.

"Very pleased!"

Overall I would recommend this item. I own 3 of these and besides my canister they are my favorite filters. Works like a dream and can't even hear it! Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. It's only rated at 25 gph less, but holds considerably less media. You do have to unplug it for those two jobs. I was worried about some of the negative reviews.

Get it and take heed to what I wrote. This lives up to the praise that people give it. I liked the clean lined look and the pull out basket. This one is working perfectly good FOR RIGHT NOW.
