Questions & Answers

I want to make sure this will fit my tank. So what is the space between the intake and the back? I am basically wondering how big the lip on the tank can be?
Answer by ChewyJul 21, 2019
The dimensions are arranged as depth (front to back) x width across x height from the bottom of filter (not including the length of the tube). The 20-gallon filter is 4.5 inches long, 7 inches wide and 6.5 inches tall. Size 30 dimensions are 4.5 x 8.2 x 6.7 inches. Size 50 dimensions are 4 x 9 x 8 inches. Size 70 dimensions are 6.2 x 10.7 x 8.6 inches. Size 110 dimensions are 7.1 x 13.9 x 9.1 inches. The part of the filter that overhangs, into the tank, is approximately 2 inches.

How long does the filter tube extend out to
Answer by ChewyFeb 06, 2018
The tube extends to 6.5 inches for the size 110 filter.

Is this filter good for betta fish?
Answer by ChewyDec 19, 2017
This product is suitable for Betta fish. The patented refiltration system allows you to control the flow rate without compromising filtration efficiency for more delicate fish and plants.

Would this be a great filter for my messy turtle
Answer by ChewySep 03, 2018
The multi-stage filtration system helps maintain a healthy tank for both fresh and saltwater aquariums.

Gets the job done!

I bought this because I was sick of using the canister filter and I had downgraded from a 55gal to a 36gal and this provided more than enough gph for that size of tank. It was great for the first 2wks then I came home to it sounding like a box of rocks. Chewy resolved that issue quickly with no worries. I received the replacement and this one was noisy. After some online research and a little Vaseline on the magnet the noise was reduced. With the lid off its almost whisper quiet. With it on there will be some humming. Apparently, it's just the brand and if that's something you can't live with don't purchase it. The sound of the water coming through will mask it after the Vaseline is applied. The other notable issue is the suction control. It is just the bottom of the intake pipe sliding across the hole. The issue is it sticks sometimes or catches as you adjust. If they were to create some kind of rubber gasket or boot that would help it slide better than plastic on plastic this would greatly improve the suction as well as the movement. Pros: Easy to maintain Affordable Media Easy Setup and Maintenance Accepts Various Media Good GPH for all sizes of tanks Cons: Noisy (until Vaseline applied) The suction selection could be better developed. Overall, I gave this 3 stars because the design can be improved to alleviate a lot of the issues. But it is a functioning power head/filter that does work. It has the water clean and crystal clear in about an hour after setup. It is a good power head/filter but could be better!

Love AquaClear

I have the larger version on my 60 gal tank and it’s great. I bought this for a smaller 20 gal.. Love how you can customize the filtration and clean easily. Chewy is great as usual!

Great filter, great customer service

I needed to upgrade from the 70 because it was too small for my tank. I was able to use a coupon on this one, but when I received it, the lid was damaged. Chewy sent out a replacement immediately. Awesome service. So far, the filter is working great.

Stopped working

After 48 hours of using this on and off, it just shut off out of no where and stopped working. Tried a lot to get it to work, cleaned out every single part but it did not work

good quiet filter

I had an emperor filter that worked well, but was very noisy. I just changed to the aqua clear and am pleased by the reduction in noise. The filter works very well and is much quieter.
