I have this filter for three small tanks, two filters i bought and the other filter came with the tank. The first one, the one that came with the tank works fine. Is quiet, keeps the water clear, doesnt make the lid go up and down or anything. As for the other two, it kept on making the lid go up and down. I also noticed they were a bit louder but I guess its just me. I use this for my bettas, does the job. This is great for small tanks.

If you are buying this for a small tank with no cut outs on the hood, this is not the filter for you. While the box calls it an internal filter and the description says, "Adjusts easily to high or low water levels with mounting suction cups"...there are no suction cups included. You open the box to find a slip of paper included that says, " NEW CLIP DESIGN!" Both the paper and responses by Tetra claim that the clip is adjustable. The filter is adjustable up and down, but there is no getting around the fact that the clip hangs over the lip if the tank. I have a tiny beta tank. There is a small notch to accommodate a air line, not a 3/4" wide clip. Many small tanks are like this. I have other pets and it's imperative that I have a tightly fitting lids. The previous version of this was truly internal and that's what I wanted, and what the box said I was getting.

I bought this to replace the pump/filter that came with my 1.5 gallon aquarium (had it for a long time, it finally died). I've had other small aquariums and this is by far the loudest pump/filter I've ever had! I'm not sure if it's defective or if it's supposed to be this loud - if so, I'm really disappointed. It seems to work in terms of filtering the water, but I cannot take the loud hum/buzz of the unit. I have to turn it off when I'm home -- it's that loud! I am actively looking for another pump/filter and don't recommend this product.

Thank you for posting your comments. We are sorry to hear that this pump is working in a noisy fashion. There is a break in period of time for air pumps of 1-2 days, and they may create more noise than usual during this time. This can also be due to a restriction such as a kinked air line, or it can be the surface the air pump is sitting on is creating a lot of reverberation. Make sure there is no restriction to the air pump and operate it on a different surface, with the filter attached, to make sure it is operating properly. If it is not, simply call the Tetra Consumer Relations Team at 1-800-526-0650 for assistance.

Good for bettas, bad attachment design

The filter works as advertised. It's good for bettas, as this will work in smaller betta tanks. I bought it for my 2 gallon hexagonal tank. My main complaint with it is the attachment. Suction cups would have been MUCH easier, but instead they changed it to a "new" clip design. IT DOES NOT clip on anything. Tanks meant for fish have a lip at the tip, meaning it's way too wide to have this ting sit at water level. Mine has the output about 1.5 inches above the water level because you physically cannot slip it any lower. That aside, it works well, and is very quiet. The only noise from mine is a very quiet hum from the bubbler, and an occasional tiny blub when bubbles reach the top of the filter. My betta is fine with it, and it's very unobtrusive for a 2 gallon tank. I would recommend it for use with smaller betta tanks, but not for use with tanks that have a rim meant for a top.

I was shopping for a small air pump to put an air stone in a one gallon tank with a snail and a few ghost shrimp. I saw this for just a couple more dollars than just the pump, so I thought I'd give it a try to see if it might be better than the filter that came with the tank. I found that the intact tube is too long for the Aqueon 1 gallon tank, especially if you have gravel in it. At first I was impressed by how much water the filter moved for it size, but less than a day later it was not working as well. It is also pretty noisy. The quality is OK, considering the price. I started to return it, but since I really needed the pump, I decided to keep it for a back up filter in case one of my other filters failed or if I needed to isolate a fish in my small sick tank. I would not recommend it for daily use.

We are sorry to hear this, as this filter is actually included in several of our 1 gallon up to 3 gallon aquarium desktop kits. it should be more than enough power to operate the system. However, if the pump is very loud, then you might be experiencing either back pressure that is causing the unit to reduce the air flow to the filter system. We would be able to help you replace the air pump if it is not working correctly. Please contact our Customer Care Line at 1-800-526-0650.
