Polar Aurora First Impressions

"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.

Polar Aurora Final Thoughts

"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.

"A very obvious waterfall."

The filter stopped working all of a sudden. Early on it seems to be working as advertised. Following morning it was running quietly. Replace activated carbon every 6-8 months ish. I checked and cleaned it and still just as loud. I had to lower the surface by 3 inches to get sufficient agitation. There must be a huge batch of these units at Amazon right now that are bad.

"This is not."

Months later, this filter is still working great on my 29 gal set up. I had to lower the surface by 3 inches to get sufficient agitation. My baby turtle even loves it so much he won't let go. This new AQ50 filter has loose bio-media, i. My tank was a mess when I got this pump. I bought a top fin 55 gallon aquarium on sale. It's easy to clean and we all know about easy.

I will pick 3-4 of these at one time over a single system any day. However, lately I've purchased the Aqua Clear 70 and 50. Typically just below the flat part of the outlets. I own 3 of these and besides my canister they are my favorite filters. Early on it seems to be working as advertised. So, easy is good, both for us and our fish.

"It's heavy and awkward."

I use Marinelands refillable cartridge for extra carbon on the extra slots. They can be very noisy at the impeller, which sometimes quiets in time, but may not. SO, I sat down and read EVERY little thing in rhe instructions. Firstly, I'd recommend taking the motor apart and putting it back together. I returned the Aqua Clear 70 and promptly received a replacement. DO NOT CLEAN OR WASH the paper wheel itself. My baby turtle even loves it so much he won't let go.

"Very pleased!"

The instructions are a bit to much for me. I contacted Marineland about my issue and they promptly sent me a new one right away! My baby turtle even loves it so much he won't let go. My fish are definitely happier and my water is crystal clear. The bacteria eats the nitrates in the water to help keep it clean. What I don't like is how much smaller it is than the Aqueon. My baby turtle even loves it so much he won't let go.

"This is not."

Of course the sound all depends on how much water is in the aquarium. First they are simple and designed to pump and filter aquarium water. My tank was a mess when I got this pump. Never ever ever use it past a year. Replace activated carbon every 6-8 months ish. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. Clean the foam insert apparently it pulled a lot of dirt and needs cleaned.

"I like the design."

You'll want to pull that water from the bottom. I will pick 3-4 of these at one time over a single system any day. Overall, I'm very happy with this filter. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. This filter comes with a sponge, activated carbon, and bio material in a mesh bag. Oscars are very messy fish, especially during feeding. Therefore, you wouldnt have 2 filters running.

"Great price."

I returned the Aqua Clear 70 and promptly received a replacement. It's only rated at 25 gph less, but holds considerably less media. I put it together, reading instructions of course. Really happy with the money I was able to save. I wasn't able to fill my tank fully because there was little to no surface agitation. Once it loses its charge, you'll need to replace it. I used to have a 37 gallon eclipse aquarium.

"SAME THING!"

I will never buy any other HOB no matter what deal they might be offering. I used to have a 37 gallon eclipse aquarium. Months later, this filter is still working great on my 29 gal set up. All in all, I highly recommend this filter and I'm a extremely happy customer! Of course the sound all depends on how much water is in the aquarium. I was using a Tetra in-tank filter previously. You can't really tell though, and the filter is working great.

"I only used one."

In the afternoon the noises started again. My old pump was not working very well so I had to make a major clean up. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter. I used to have a 37 gallon eclipse aquarium. With the 350's inexpensive price point, you can’t go wrong with this powerful filter. Unlike my old HOB filter, it doesn't sound like a leaky toilet. MAKE SURE YOU PUT WATER IN THE BACK OF THE FILTER!

  • Intsun Aquarium Filter, Aquarium Sponge Filter Moving Bed Media Filter Fluidised Bed Filter for Fish Tanks
  • 【Multi-filtration functions】Imitating the riverbed in nature, the sandstone rolls with the flow of water on the riverbed, and the nitrifying bacteria breed in one generation and one generation, which plays a role in purifying the water.

No need to replace the filter material during usage period
  • 【Fits fish tank size: 20 to 40 gallon】Easy to set up: simply install an airline tube into the unit and turn on the air pump,comes with 4 suction cups,can be easily installed anywhere of the aquarium; suitable for shrimp tank, betta tank, breeding tank, fry tank, goldfish, discus, guppies, baby fish or other fish.
  • 【Easy to use】 Using an air hose, connect one end to you air pump and the other end to this filter. The water flow exit tube on the sponge filter is adjustable so you can change direction and height of the water flow
  • 【Removable Fine Sponges 】you can easy to take down the 2 sponges from the filter to clean or replace it, the 2 sponges are fine 60ppi not coarse, which means more surface area for beneficial bacteri to live on. Don't use tap water to clean it, just rinse or squeeze the sponges by using the aquarium water

So, easy is good, both for us and our fish. The filter stopped working all of a sudden. Once I found that, the world was right again. I've looked at so many filters and reviews. This filter really does a good job. Once I found that, the world was right again. The ability to regulate the flow solves the loud waterfall problem.

Lightly clean the silver roller pins on the ends. A canister or in tank filter is ten times more work and messy. The bacteria eats the nitrates in the water to help keep it clean. Works like a dream and can't even hear it! I own 3 of these and besides my canister they are my favorite filters. Following morning it was running quietly. , that's what makes this so funny.

"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.

"No worries there."

Also price was very reasonable and shipping was fast. I have 4 other AquaClear filters and like them. Once it loses its charge, you'll need to replace it. I decided to go with this filter since I had a positive experience previously. Fill up the media slot with water until it's full. My tank was a mess when I got this pump. I've think I've had had six of them.

This filter has is a very simple and efficient design. Not sure what I'll do with the more complex design. There is a sound from the water shooting into the tank! I had a lot of particles in the water. My fish are definitely happier and my water is crystal clear. That water got so dirty we had to keep changing it every 2 or 3 days. Firstly, I'd recommend taking the motor apart and putting it back together.
