AA Aquarium AAUV9W First Impressions

"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.

"In one day crystal clear."

My baby turtle even loves it so much he won't let go. I wasn't able to fill my tank fully because there was little to no surface agitation. I've been researching so many things on how to take care of them. This filter really does a good job. Controlling the flow rate doesn't require modifying the filter. The Marineland penguin 350 is a great filter. Clean the foam insert apparently it pulled a lot of dirt and needs cleaned.

I had to cut the hood to make it work. It wasn't producing much surface agitation. Therefore, you wouldnt have 2 filters running. The filter stopped working all of a sudden.

"I should loosen it up."

, that's what makes this so funny. I ordered 4 of these, for different tanks of course. The filter arrived within 2 days and was the exact same as Petsmart's. However, lately I've purchased the Aqua Clear 70 and 50. I put it together, reading instructions of course. I have the topfin 29 gallon tank and used the HOB filter it came with. I used a small pair of pliers and carefully got the pebbles out.

"- Plug it into power."

I've looked at so many filters and reviews. Firstly, I'd recommend taking the motor apart and putting it back together. I've looked at so many filters and reviews. DO NOT CLEAN OR WASH the paper wheel itself. I used to work as a marine biologist for a major state aquarium. I was new to the hobby and didn't realize that Tetras were inferior filters.

It also has a media container with a ceramic filter inside to help eliminate harmful substances and provide additional cleaning power. Other filters can be replaced.

The outlet pipe in the sponge filter can be adjusted so that you can change the direction and height of the water flow (not including the pump and air hose, please choose a powerful pump for this filter according to your tank size).

"Seriously."

I wasn't able to fill my tank fully because there was little to no surface agitation. Not sure what I'll do with the more complex design. My fish are definitely happier and my water is crystal clear. Once I found that, the world was right again. You'll want to pull that water from the bottom. My tank is nice and clear and my fish are much happier. Of course the sound all depends on how much water is in the aquarium.

"I love this canister."

I own 3 of these and besides my canister they are my favorite filters. The first night I had the pump going it started making a screeching sound. If that does not work, look into silicone grease so you can lube the impeller. Firstly, I'd recommend taking the motor apart and putting it back together. I've looked at so many filters and reviews.
