The AquaClear CycleGuard Power Filter is a versatile clip-on filter that uses a multi-stage filtration system to improve water quality. The CycleGuard system provides three types of filtration: mechanical, chemical and biological. In this unique system, only one component is changed at a time to protect the beneficial bacteria that’s usually thrown out with cartridge filtration systems. The AquaClear CycleGuard Power Filter comes with AquaClear Foam, Activated Carbon and BioMax filter inserts. As the water filters through, these inserts help preserve good bacteria, trap debris and remove impurities for a stress-free environment. The patented refiltration feature lets you control the flow rate for more delicate fish and plants.

Aquarclear 110 works fine but I'm returning the 70
on Feb 19, 2021
I didn't order this filter from Chewy but I've only had it for 4 months and can't stand that you have to clean the motor every time, other wise it doesn't work. Ive tried running the motor in different outlets and it would go back and forth between running and not running. Ive had Aquaclear filters before and have never dealt with a messed up motor, plus it doesn't make sense to ONLY replace the motor because a motor for the 70 cost the exact SAME as the filter. Just make sense to return the whole thing to get a full refund.
Don’t buy if you have sand

I can’t speak for a gravel tank, but I’m pretty sure the malfunctioning is from sand getting stuck in the motor. After a few months, it started making a loud noise and then just quit working. I cleaned it out as much as I could, and was able to get it spinning again, but it’s still loud and making a buzzing sound. It will die again soon. I now have to find a filter that will work for a sand bottom tank and spend even more money. It makes me sad because I liked this filter and the three step filtration.
Best ones for my tanks thus far

I've used so many weak types over the years, Whisper, Marineland and so on. Within 2 hrs of using my 110 version on my new 55 gallon tank, it was a huge relief to see it work so well. Just in the past year with Marineland specifically, 6 units and none of them worked that well and all failed miserably. With Aquaclear you have a clear, see thru media box and lets you see everything that goes into that system. Fish are super happy and the tank is top notch. Hence why I went with the Aquaclear 70 as well for my other tank. It is doing awesome as well.

I swear by these filters and it’s the only thing I use on all four of my tanks!! The perfect on my over stocked goldfish tanks too!! I love how they have the extra space to pack in your own sponges or media. I’ll never use anything else.

1st one I ordered had a hole in the tub. I sent an email & got a response the same day. A few days later it was delivered to my house, undamaged and it's in my tank now.

The aquaclear filter are very good and I really like them.
I just wish fluval would change the plastic in them to a better type so the plastic would not break as easy other wise I would have given them a 5 star.
Thanks chewy for a great price. By far the best price I have every seen on a aquaclear 300.

This is the best filter on the market. I have used them for years along with Marineland and Whisper. The latter two used to be good filters but they are now manufactured very cheaply and are poor quality. Aquaclear is by far the best.
Best HOB filter

I've tried a few other popular hang on back filters, and this is my favorite. I suggest going bigger, I bought two 50 versions for my 40 gallon breeder aquarium. While one is being cleaned, I can keep the other filter running. But one 110 might have been even better. Either way, you can't go wrong with this filter.
It works really well

The adjustable flow makes an easy way to control the filtration of the water on my fish tank. It’s a good buy and a great product
the best filter I have ever used
on Aug 24, 2020
I have tried multiple types and brands but never got the type of crisp clean aquarium for my fish I’ve always sought, requiring me to get water clarifying additives which didn’t help much. I then ran this filter system and was literally shocked at how efficient, quiet not to mention super easy to clean it was. And reusable filtering system which beats the useless padding inserts that come with other systems made my tank sparkling clean & really caught me by surprise. I ran two store bought brand name traditional filters for 30gal + 10-20gal on one tank for a while, the gave them a rest and ran AquaClear by itself and it beat their performance hands down.

My fish are much happier and healthier, and the transparent casing shows me the condition of the filters without even having to pull them out. I’m now reinstalling my other tanks and replacing their filtering system with AquaClear. 1000% recommended. Also Chewy’s pricing on the item and the filters keeps me happy :D… more
