"This thing is a beast."

It was perfectly quiet without any extra effort on my part. They can be very noisy at the impeller, which sometimes quiets in time, but may not. That water got so dirty we had to keep changing it every 2 or 3 days. The current is strong but you can adjust it with the midsection lever. I stopped the pump and I pulled it apart. I wasn't able to fill my tank fully because there was little to no surface agitation. I can hear it 3 rooms away grinding away.

"Just a tip!"

I want to answer some of the complaints I've read. I'm a mechanical engineer and understand design. Once it loses its charge, you'll need to replace it. This one is working perfectly good FOR RIGHT NOW. Doing research I learned that if I add more filter media, the noise will subside. I took it apart reassemble it and it's not pumping in the water. It's easy to clean and we all know about easy.

2. Koi Pond and Aquarium Filter Pad Media Roll - Blue Bonded - 12 inches by 72 inches (6 ft) by 1 inch ...

AirstarFilters BW_12"_6Feet First Impressions

"A THUMBS UP."

This is a good choice if you're tired of cleaning your turtle tank all the time. I'd highly recommend not replacing the bio material& sponge, ever. Fill up the media slot with water until it's full. That water got so dirty we had to keep changing it every 2 or 3 days. If that does not work, look into silicone grease so you can lube the impeller. Oscars are very messy fish, especially during feeding. I liked the clean lined look and the pull out basket.

"My fault not theirs."

The Marineland penguin 350 is a great filter. Your fish and you will be much happier and stun everyone else. As for performance, I couldn't ask for a better filter. It sounds like a Big Air pump buzzing. I AM IMPRESSED THAT IT WORKS AS IT ACTUALLY SHOULD! Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER!

"This filter is perfect!"

I own 3 of these and besides my canister they are my favorite filters. I bought a top fin 55 gallon aquarium on sale. I thought that U had put it together wrong so I took it all apart and started over. I put it together, reading instructions of course. They can be very noisy at the impeller, which sometimes quiets in time, but may not. They are easily found from mom-n-pop pet stores to large chain stores. The Aqua Clear is on the left and the Aqueon is on the right.

"Added 3 baby turtles."

Months later, this filter is still working great on my 29 gal set up. Overall, I'm very happy with this filter. I also don't like how short the intake tube is. I had a lot of particles in the water. I bought a top fin 55 gallon aquarium on sale. I have the topfin 29 gallon tank and used the HOB filter it came with. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests.

"The product itself."

I have contacted customer service to see if I can get a replacement unit. I will pick 3-4 of these at one time over a single system any day. In the afternoon the noises started again. This filter has is a very simple and efficient design. All in all, I highly recommend this filter and I'm a extremely happy customer! Therefore, you wouldnt have 2 filters running.

"In one day crystal clear."

Of course the sound all depends on how much water is in the aquarium. My fish are definitely happier and my water is crystal clear. Fill it up with water before you plug it in. I want to answer some of the complaints I've read. The bacteria eats the nitrates in the water to help keep it clean. Now I'm having the same issue with the Aqua Clear 50. Once it loses its charge, you'll need to replace it.

I use Marinelands refillable cartridge for extra carbon on the extra slots. I had to cut the hood to make it work. I still have my original wheels on the year old 350 with no issues whatsoever.

This is a well designed unit and a lot of bang for the buck. SO, I sat down and read EVERY little thing in rhe instructions. , that's what makes this so funny.

"Disappointing."

I can hear it 3 rooms away grinding away. SO, I sat down and read EVERY little thing in rhe instructions. I will never buy any other HOB no matter what deal they might be offering. It doesn't rise up hugely above the tank like a lot of HOB filters. I've think I've had had six of them. I'm currently in the process of receiving another replacement on that model. I ordered 4 of these, for different tanks of course.

"It's priced awesome!"

Worst case is that the motor could burn out. This one is working perfectly good FOR RIGHT NOW. There is a sound from the water shooting into the tank! My old pump was not working very well so I had to make a major clean up. Works like a dream and can't even hear it! If that does not work, look into silicone grease so you can lube the impeller. Overall, I'm very happy with this filter.

"That also didn't work."

As for performance, I couldn't ask for a better filter. This lives up to the praise that people give it. This is a well designed unit and a lot of bang for the buck. I can take apart a car engine and put it back together. The first night I had the pump going it started making a screeching sound. I was worried about some of the negative reviews. I still have my original wheels on the year old 350 with no issues whatsoever.

"This one does!"

Get it and take heed to what I wrote. I checked and cleaned it and still just as loud. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. I had originally got one for my 75 Gallon tank housing an Oscar. DO NOT CLEAN OR WASH the paper wheel itself. They were great to deal with and the new filter is working great! Get it and take heed to what I wrote.

"If anyone knows turtles."

Fill it up with water before you plug it in. The Aqua Clear is on the left and the Aqueon is on the right. You do have to unplug it for those two jobs. The bacteria eats the nitrates in the water to help keep it clean. However, lately I've purchased the Aqua Clear 70 and 50. SO I decided to order this for my 29 gallon tank. My baby turtle even loves it so much he won't let go.
