"Great product."

Worst case is that the motor could burn out. Also price was very reasonable and shipping was fast. I'm a mechanical engineer and understand design. It wasn't producing much surface agitation. Oscars are very messy fish, especially during feeding. Works like a dream and can't even hear it! Following morning it was running quietly.

AQUANEAT SF-A010x4^^ Final Thoughts

"Came on time."

They are simply the best design for nitrifying bacteria to grow on. It started out silent for about 30 mins and then it got super loud. I was new to the hobby and didn't realize that Tetras were inferior filters. The current is strong but you can adjust it with the midsection lever. It's easy to clean and we all know about easy. I eyedball everything and put it together with a look back at instructions. I had originally got one for my 75 Gallon tank housing an Oscar.

"Since then no problems."

This is not my first experience with a marineland filter. That water got so dirty we had to keep changing it every 2 or 3 days. Oscars are very messy fish, especially during feeding. Also price was very reasonable and shipping was fast. I own 3 of these and besides my canister they are my favorite filters. DO NOT CLEAN OR WASH the paper wheel itself. Early on it seems to be working as advertised.

AQUANEAT Final Thoughts

"It's heavy and awkward."

You do have to unplug it for those two jobs. You can't really tell though, and the filter is working great. Oscars are very messy fish, especially during feeding. I ordered 4 of these, for different tanks of course. I've think I've had had six of them. My tank is nice and clear and my fish are much happier. I used to work as a marine biologist for a major state aquarium.

"Not ideal but it works."

Worst case is that the motor could burn out. Therefore, you wouldnt have 2 filters running. The ability to regulate the flow solves the loud waterfall problem. I will never buy any other HOB no matter what deal they might be offering. I have contacted customer service to see if I can get a replacement unit. I used to have a 37 gallon eclipse aquarium. Fill it up with water before you plug it in.

"No effect."

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. The filter stopped working all of a sudden. I have purchased several Aqua Clear filters over the years. SO I decided to order this for my 29 gallon tank.

"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.

"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.

"If anyone knows turtles."

The current is strong but you can adjust it with the midsection lever. As for performance, I couldn't ask for a better filter. I thought that U had put it together wrong so I took it all apart and started over. It sounds like a Big Air pump buzzing. Therefore, you wouldnt have 2 filters running. Also the maker should review the pump design. They are easily found from mom-n-pop pet stores to large chain stores.

"This is not."

I stopped the pump and I pulled it apart. I contacted Marineland about my issue and they promptly sent me a new one right away! They can be very noisy at the impeller, which sometimes quiets in time, but may not. I eyedball everything and put it together with a look back at instructions. The current is strong but you can adjust it with the midsection lever. This filter has is a very simple and efficient design. If that does not work, look into silicone grease so you can lube the impeller.

"It's priced awesome!"

This is not my first experience with a marineland filter. Doing research I learned that if I add more filter media, the noise will subside. I put it together, reading instructions of course. The filter stopped working all of a sudden. This one is working perfectly good FOR RIGHT NOW. This is not my first experience with a marineland filter.

"- Plug it into power."

The first night I had the pump going it started making a screeching sound. Of course the sound all depends on how much water is in the aquarium. I've think I've had had six of them. I'm currently in the process of receiving another replacement on that model. 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. The instructions are a bit to much for me.

"Since then no problems."

A canister or in tank filter is ten times more work and messy. Fill up the media slot with water until it's full. Not sure what I'll do with the more complex design. Following morning it was running quietly. I thought that U had put it together wrong so I took it all apart and started over. Overall I would recommend this item. Once I found that, the world was right again.

"Thanks, AquaTech."

I'm currently in the process of receiving another replacement on that model. I used to work as a marine biologist for a major state aquarium. That water got so dirty we had to keep changing it every 2 or 3 days. Months later, this filter is still working great on my 29 gal set up. Never ever ever use it past a year. One thing I think is worth mentioning is the need to prime the filter. That water got so dirty we had to keep changing it every 2 or 3 days.

"Came on time."

I used to work as a marine biologist for a major state aquarium. That water got so dirty we had to keep changing it every 2 or 3 days. I can take apart a car engine and put it back together. I had to lower the surface by 3 inches to get sufficient agitation. The first night I had the pump going it started making a screeching sound. My tank was a mess when I got this pump. I have contacted customer service to see if I can get a replacement unit.

"All around great product."

The current is strong but you can adjust it with the midsection lever. I use Marinelands refillable cartridge for extra carbon on the extra slots. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER! The first night I had the pump going it started making a screeching sound. I also don't like how short the intake tube is. Once it loses its charge, you'll need to replace it. I thought that U had put it together wrong so I took it all apart and started over.
