"Just a low hum."

I have had no issues with it being to loud. Overall, I'm very happy with this filter. Never ever ever use it past a year. They are simply the best design for nitrifying bacteria to grow on. I'd highly recommend not replacing the bio material& sponge, ever. Firstly, I'd recommend taking the motor apart and putting it back together. It started out silent for about 30 mins and then it got super loud.

  • 10-Gallon Betta Sponge Filter, Underwater Center Aquarium Filter, Works for Tropical Fish & Breeder Aquarium, Slow current, Perfect for Fry & Small Fish, Must-have for Aquarium Hobbyist
  • REPLACE THE TRADITIONAL HOB, CANISTER FILTERS --- Gone are the days when you got to change the cartridges and filter media almost every week. The handy filter by SunGrow will do the same job economically and quickly.
  • SPECIALLY DESIGNED FOR BETTA, FRY & OTHER SMALL AQUATIC PETS --- Betta, fry and other small fish will NEVER get stuck up into the filter. These fish, especially Betta, generally don’t like vigorous currents, they prefer calm and steady water. This filter is designed to have slow current to easily let betta, goldfish discus, dwarf cichlids, guppies, and krill fish, continue breeding and spawning comfortably.
  • PROVIDE SUPPLEMENTAL FOOD FOR FRY --- The minor bubbles that are created by this sponge filter creates a nominal current, adding in bubbling water. This will encourage them to continue breeding and spawning comfortably. Also, the sponge filter makes a home for fish food supplementing their daily dose of diet or food intake.
  • PERFECT FOR UP TO 10.5 GALLON TANK WHEN USED SINGLY --- It only requires an air pump and airline tubing (sold separately) to work. These create numerous minute bubbles for increased oxygen flow. Simply connect an air pump to the top-center of the filter, then place it in your tank. Please note, the base of this noiseless filter is not weighted, so you may need to weigh it down. It is suitable for tanks up to size 10.5 gallons. Use 2 or more filters in larger tanks.
  • EASY TO WASH & REUSE --- This low-cost sponge filter can be used multiple times. Instead of tap water, use water from the tank to clean it, during a water change. Simply rinse and squeeze a few times, until you see the water run clear from the sponge.

SunGrow Final Thoughts

"So who knows."

My old pump was not working very well so I had to make a major clean up. This filter really does a good job. Once I found that, the world was right again. The filter stopped working all of a sudden. There must be a huge batch of these units at Amazon right now that are bad. The instructions are a bit to much for me. I have the topfin 29 gallon tank and used the HOB filter it came with.

"And SILENCE."

SO I decided to order this for my 29 gallon tank. My fish are definitely happier and my water is crystal clear. There must be a huge batch of these units at Amazon right now that are bad. , that's what makes this so funny. I was also having oxygen issues because of this. BUT after some YouTube research I was able to fix the noise issue. I can hear it 3 rooms away grinding away.

SunGrow Final Thoughts

"I bought an FX6 in 2013."

My old pump was not working very well so I had to make a major clean up. Fill up the media slot with water until it's full. I put it together, reading instructions of course. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. The Aqua Clear is on the left and the Aqueon is on the right. I used to have a 37 gallon eclipse aquarium. Controlling the flow rate doesn't require modifying the filter.

"This thing is a beast."

It started out silent for about 30 mins and then it got super loud. I stopped the pump and I pulled it apart. I used a small pair of pliers and carefully got the pebbles out. Oscars are very messy fish, especially during feeding. Basically, make sure everything that is suppose to spin, does so smoothly. Fill up the media slot with water until it's full. It sounds like a Big Air pump buzzing.

SunGrow Final Thoughts

"Just a low hum."

I've think I've had had six of them. I had a lot of particles in the water. However, lately I've purchased the Aqua Clear 70 and 50. I will never buy any other HOB no matter what deal they might be offering. My box came in good condition, parts where in tact and new. Typically just below the flat part of the outlets. I use Marinelands refillable cartridge for extra carbon on the extra slots.

"Just a tip!"

Now I'm having the same issue with the Aqua Clear 50. Oscars are very messy fish, especially during feeding. I bought a top fin 55 gallon aquarium on sale. The lever on the bottom helps even the filter out. I liked the clean lined look and the pull out basket. I used to have a 37 gallon eclipse aquarium. My fish are definitely happier and my water is crystal clear.

"Like brand new."

The Marineland penguin 350 is a great filter. Overall I would recommend this item. Unlike my old HOB filter, it doesn't sound like a leaky toilet. This is a well designed unit and a lot of bang for the buck. I DONT KNOW WHY MANY THINK THIS IS A NOISY FILTER. I was also having oxygen issues because of this. The current is strong but you can adjust it with the midsection lever.

I can hear it 3 rooms away grinding away. First they are simple and designed to pump and filter aquarium water. BUT after some YouTube research I was able to fix the noise issue. Overall, I'm very happy with this filter. I stopped the pump and I pulled it apart. All in all, I highly recommend this filter and I'm a extremely happy customer! DO NOT CLEAN OR WASH the paper wheel itself.

"I should loosen it up."

I'm a mechanical engineer and understand design. I AM IMPRESSED THAT IT WORKS AS IT ACTUALLY SHOULD! In the afternoon the noises started again. One thing I think is worth mentioning is the need to prime the filter. 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. I'm currently in the process of receiving another replacement on that model.

"I bought an FX5 in 2011."

What I don't like is how much smaller it is than the Aqueon. I attempted to clean and lube the impeller, but to no avail. If that does not work, look into silicone grease so you can lube the impeller. I will never buy any other HOB no matter what deal they might be offering. I stopped the pump and I pulled it apart. This filter has is a very simple and efficient design. Also the maker should review the pump design.

I will never buy any other HOB no matter what deal they might be offering. The first night I had the pump going it started making a screeching sound. My old pump was not working very well so I had to make a major clean up. Doing research I learned that if I add more filter media, the noise will subside. Get it and take heed to what I wrote. Also price was very reasonable and shipping was fast. I also like the fact that it is relatively low profile and discreet looking.

"My fault not theirs."

SO I decided to order this for my 29 gallon tank. You can't really tell though, and the filter is working great. A canister or in tank filter is ten times more work and messy. So, easy is good, both for us and our fish. This one is working perfectly good FOR RIGHT NOW. It doesn't rise up hugely above the tank like a lot of HOB filters. I want to answer some of the complaints I've read.
