"That also didn't work."

This new AQ50 filter has loose bio-media, i. My old pump was not working very well so I had to make a major clean up. I was worried that it might be too much for my aquarium or that it would be loud.

First they are simple and designed to pump and filter aquarium water.

"Try it you wont be sorry."

The Marineland penguin 350 is a great filter. Never ever ever use it past a year. The filter stopped working all of a sudden. Also price was very reasonable and shipping was fast. I have purchased several Aqua Clear filters over the years. I was worried about some of the negative reviews. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon.

"And SILENCE."

If that does not work, look into silicone grease so you can lube the impeller. Get it and take heed to what I wrote. However, lately I've purchased the Aqua Clear 70 and 50. Overall I would recommend this item. This filter has is a very simple and efficient design. It was perfectly quiet without any extra effort on my part. I eyedball everything and put it together with a look back at instructions.

"5 minutes."

My tank is nice and clear and my fish are much happier. Fill up the media slot with water until it's full. I use Marinelands refillable cartridge for extra carbon on the extra slots. Typically just below the flat part of the outlets. You can't really tell though, and the filter is working great. You'll want to pull that water from the bottom. My baby turtle even loves it so much he won't let go.

Controlling the flow rate doesn't require modifying the filter. Just rinse them out once a month, don't throw that beneficial bacteria away. Controlling the flow rate doesn't require modifying the filter. I have always used Marineland filters and been happy with them and their quality. It doesn't rise up hugely above the tank like a lot of HOB filters. You'll want to pull that water from the bottom. Marineland bio pumps have been around forever.

"This is the one."

I was worried about some of the negative reviews. This is a well designed unit and a lot of bang for the buck. Firstly, I'd recommend taking the motor apart and putting it back together. Early on it seems to be working as advertised. I've been researching so many things on how to take care of them. My tank was a mess when I got this pump. Your fish and you will be much happier and stun everyone else.

"The product itself."

I've looked at so many filters and reviews. I have always used Marineland filters and been happy with them and their quality. Your fish and you will be much happier and stun everyone else. This is not my first experience with a marineland filter. They can be very noisy at the impeller, which sometimes quiets in time, but may not. I was using a Tetra in-tank filter previously. My tank was a mess when I got this pump.

"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.

"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.

Firstly, I'd recommend taking the motor apart and putting it back together. I use Marinelands refillable cartridge for extra carbon on the extra slots.

"Yeah, no no no!"

They can be very noisy at the impeller, which sometimes quiets in time, but may not. I will never buy any other HOB no matter what deal they might be offering. The filter arrived within 2 days and was the exact same as Petsmart's. This filter comes with a sponge, activated carbon, and bio material in a mesh bag. The first night I had the pump going it started making a screeching sound. This lives up to the praise that people give it. Early on it seems to be working as advertised.

"Expensive."

I used to have a 37 gallon eclipse aquarium. I will pick 3-4 of these at one time over a single system any day. I was worried that it might be too much for my aquarium or that it would be loud. It wasn't producing much surface agitation. I was worried about some of the negative reviews. Just rinse them out once a month, don't throw that beneficial bacteria away. BUT after some YouTube research I was able to fix the noise issue.

The lever on the bottom helps even the filter out. Early on it seems to be working as advertised. My box came in good condition, parts where in tact and new.

"Best to you all!"

Worst case is that the motor could burn out. I use Marinelands refillable cartridge for extra carbon on the extra slots. 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! One thing I think is worth mentioning is the need to prime the filter. The instructions are a bit to much for me. It sounds like a Big Air pump buzzing.

"Piece of cake!"

I ordered 4 of these, for different tanks of course. Fill up the media slot with water until it's full. I checked and cleaned it and still just as loud. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER! I returned the Aqua Clear 70 and promptly received a replacement. My tank was a mess when I got this pump. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges.

"And it is so quiet."

Worst case is that the motor could burn out. This filter comes with a sponge, activated carbon, and bio material in a mesh bag. It's only rated at 25 gph less, but holds considerably less media. Months later, this filter is still working great on my 29 gal set up. Oscars are very messy fish, especially during feeding. Once I found that, the world was right again. One thing I think is worth mentioning is the need to prime the filter.

They were great to deal with and the new filter is working great! This filter comes with a sponge, activated carbon, and bio material in a mesh bag. I used a small pair of pliers and carefully got the pebbles out. This is not my first experience with a marineland filter. I had a lot of particles in the water.
