"Like brand new."

My tank is nice and clear and my fish are much happier. I had to cut the hood to make it work. I will never buy any other HOB no matter what deal they might be offering. So, easy is good, both for us and our fish. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. It started out silent for about 30 mins and then it got super loud. My baby turtle even loves it so much he won't let go.

SUN 07102 Final Thoughts

"A THUMBS UP."

A canister or in tank filter is ten times more work and messy. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter. I will never buy any other HOB no matter what deal they might be offering. However, lately I've purchased the Aqua Clear 70 and 50. I ordered 4 of these, for different tanks of course. This one is working perfectly good FOR RIGHT NOW. However, lately I've purchased the Aqua Clear 70 and 50.

"SAME THING!"

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. I sent a request for replacement and one came the next day. I want to answer some of the complaints I've read. Never ever ever use it past a year. , that's what makes this so funny. The instructions are a bit to much for me.

SUN HW-703B PRO Final Thoughts

"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.

"Its AMAZING."

You do have to unplug it for those two jobs. You'll want to pull that water from the bottom. With the 350's inexpensive price point, you can’t go wrong with this powerful filter. Not sure what I'll do with the more complex design. They were great to deal with and the new filter is working great! This is not my first experience with a marineland filter. I'm a mechanical engineer and understand design.

"This thing is a beast."

The lever on the bottom helps even the filter out. I sent a request for replacement and one came the next day. Clean the foam insert apparently it pulled a lot of dirt and needs cleaned. Also price was very reasonable and shipping was fast. In the afternoon the noises started again. You can't really tell though, and the filter is working great. This filter really does a good job.

The filter stopped working all of a sudden. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. I attempted to clean and lube the impeller, but to no avail. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. It wasn't producing much surface agitation. It wasn't producing much surface agitation.

You can't really tell though, and the filter is working great. Really happy with the money I was able to save. I also don't like how short the intake tube is.

Aqueon 100106970 Final Thoughts

"So far so good!"

Following morning it was running quietly. The Marineland penguin 350 is a great filter. I was new to the hobby and didn't realize that Tetras were inferior filters. What I don't like is how much smaller it is than the Aqueon. This is not my first experience with a marineland filter. I want to answer some of the complaints I've read. BUT after some YouTube research I was able to fix the noise issue.

"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.

"No big deal."

My old pump was not working very well so I had to make a major clean up. They are simply the best design for nitrifying bacteria to grow on. The bacteria eats the nitrates in the water to help keep it clean. I decided to go with this filter since I had a positive experience previously. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER! I've looked at so many filters and reviews. Months later, this filter is still working great on my 29 gal set up.
