"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.

"Great price."

As for performance, I couldn't ask for a better filter. I returned the Aqua Clear 70 and promptly received a replacement. Lightly clean the silver roller pins on the ends. I've think I've had had six of them. I also like the fact that it is relatively low profile and discreet looking. Typically just below the flat part of the outlets. I can hear it 3 rooms away grinding away.

"I only used one."

This filter really does a good job. Not sure what I'll do with the more complex design. My baby turtle even loves it so much he won't let go. I was new to the hobby and didn't realize that Tetras were inferior filters. I also don't like how short the intake tube is. I also like the fact that it is relatively low profile and discreet looking. It started out silent for about 30 mins and then it got super loud.

"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.

"Yeah, no no no!"

Typically just below the flat part of the outlets. Following morning it was running quietly. My tank was a mess when I got this pump. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. I wasn't able to fill my tank fully because there was little to no surface agitation. SO, I sat down and read EVERY little thing in rhe instructions. Of course the sound all depends on how much water is in the aquarium.

"This is the one."

I'm a mechanical engineer and understand design. I sent a request for replacement and one came the next day. Basically, make sure everything that is suppose to spin, does so smoothly. What I don't like is how much smaller it is than the Aqueon. SO I decided to order this for my 29 gallon tank. First they are simple and designed to pump and filter aquarium water. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter.

Overall I would recommend this item. I have had no issues with it being to loud. I checked and cleaned it and still just as loud. I had to cut the hood to make it work.

My tank is nice and clear and my fish are much happier. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. Works like a dream and can't even hear it!

"Just a low hum."

I've looked at so many filters and reviews. The filter stopped working all of a sudden. Therefore, you wouldnt have 2 filters running. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. There must be a huge batch of these units at Amazon right now that are bad. Also the maker should review the pump design. However, lately I've purchased the Aqua Clear 70 and 50.

"Suuuuupppeeerrrr Quiet."

I was worried that it might be too much for my aquarium or that it would be loud. The current is strong but you can adjust it with the midsection lever. Get it and take heed to what I wrote. I have always used Marineland filters and been happy with them and their quality. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. I used a small pair of pliers and carefully got the pebbles out. Fill up the media slot with water until it's full.

"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 will never buy any other HOB no matter what deal they might be offering. Controlling the flow rate doesn't require modifying the filter.
