AquaClear A610 First Impressions

"SAME THING!"

Lightly clean the silver roller pins on the ends. It's easy to clean and we all know about easy. It sounds like a Big Air pump buzzing. Following morning it was running quietly. It started out silent for about 30 mins and then it got super loud. I thought that U had put it together wrong so I took it all apart and started over. I had a lot of particles in the water.

AquaClear A610 Final Thoughts

"Thats whats☝ up!"

I've think I've had had six of them. The first night I had the pump going it started making a screeching sound. Once I found that, the world was right again. Fill up the media slot with water until it's full. My fish are definitely happier and my water is crystal clear. Once I found that, the world was right again. Never ever ever use it past a year.

"All around great product."

I also like the fact that it is relatively low profile and discreet looking. The Aqua Clear is on the left and the Aqueon is on the right. Get it and take heed to what I wrote. They can be very noisy at the impeller, which sometimes quiets in time, but may not. I have contacted customer service to see if I can get a replacement unit. With the 350's inexpensive price point, you can’t go wrong with this powerful filter. I will pick 3-4 of these at one time over a single system any day.

"Huge capacity."

With the 350's inexpensive price point, you can’t go wrong with this powerful filter. I can take apart a car engine and put it back together. The instructions are a bit to much for me. This filter really does a good job. I still have my original wheels on the year old 350 with no issues whatsoever. This is a well designed unit and a lot of bang for the buck. One thing I think is worth mentioning is the need to prime the filter.

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. All in all, I highly recommend this filter and I'm a extremely happy customer! I own 3 of these and besides my canister they are my favorite filters. I'm a mechanical engineer and understand design. 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.

"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.

I took it apart reassemble it and it's not pumping in the water. Your fish and you will be much happier and stun everyone else. , that's what makes this so funny.

"No worries there."

Just rinse them out once a month, don't throw that beneficial bacteria away. It's easy to clean and we all know about easy. The filter arrived within 2 days and was the exact same as Petsmart's. I can take apart a car engine and put it back together. DO NOT CLEAN OR WASH the paper wheel itself. I checked and cleaned it and still just as loud. I also like the fact that it is relatively low profile and discreet looking.

"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. Basically, make sure everything that is suppose to spin, does so smoothly.

"No worries there."

Controlling the flow rate doesn't require modifying the filter. They can be very noisy at the impeller, which sometimes quiets in time, but may not. I wasn't able to fill my tank fully because there was little to no surface agitation. As for performance, I couldn't ask for a better filter. The Aqua Clear is on the left and the Aqueon is on the right. My tank was a mess when I got this pump. The only thing you hear is the water and even that is a soothing sound.

I want to answer some of the complaints I've read. I put it together, reading instructions of course. My fish are definitely happier and my water is crystal clear. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. , that's what makes this so funny. They are simply the best design for nitrifying bacteria to grow on.

"This thing is super loud!"

It was perfectly quiet without any extra effort on my part. 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. The instructions are a bit to much for me. The bacteria eats the nitrates in the water to help keep it clean. I can hear it 3 rooms away grinding away. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER!

"A THUMBS UP."

I checked and cleaned it and still just as loud. As for performance, I couldn't ask for a better filter. Now I'm having the same issue with the Aqua Clear 50. You CAN rinse the old ones in an emergency. If that does not work, look into silicone grease so you can lube the impeller. Of course the sound all depends on how much water is in the aquarium. I'd highly recommend not replacing the bio material& sponge, ever.

"Seriously."

The current is strong but you can adjust it with the midsection lever. This new AQ50 filter has loose bio-media, i. SO, I sat down and read EVERY little thing in rhe instructions. I used to have a 37 gallon eclipse aquarium. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER! The lever on the bottom helps even the filter out. This is a good choice if you're tired of cleaning your turtle tank all the time.
