## Description

desertcart.com AquaClear Power FilterThe AquaClear Power Filter represents one of the most versatile hang-on filter systems available. The five models available provide a complete selection of flow rates for the most popular sizes of aquariums. The filter’s unique design allows for up to six times more media volume and the longest water to media contact time in the industry.Superior Contact with AquaClear FilterPatented Re-filtration System Sometimes delicate fish and plants require a more gentle water flow. The patented AquaClear re-filtration system allows you to control the flow rate without compromising filtration efficiency. When the flow rate is reduced, up to 50% of the water within the filter chamber is processed multiple times.CycleGuard Multi-Stage Filtration System Provides optimal mechanical, chemical, and biological filtration. A healthy aquarium requires "beneficial" bacteria. Invisible and harmless, beneficial bacteria are essential in the removal of toxic ammonia and nitrite. With cartridge filtration systems, when you throw away the cartridge, you throw away beneficial bacteria. It can take weeks for the bacteria to re-colonize, resulting in a stressful environment.Typical Filter Media Placement:BottomAquaClear Foam Insert, which does the following: 1. Helps with debris removal and provides optimal water distribution patterns, allowing subsequent filter media to perform at full efficiency. 2. Biological filtration, due to the porous structure of foam, providing surfaces for beneficial bacteria.MiddleAquaClear Activated Carbon Filter Inserts contain 100% premium research grade carbon. Premium research grade carbon provides large amounts of surface area for adsorption of undesirable impurities.TopAquaClear BioMax Filter Inserts contain BioMax ceramic rings. The surface of BioMax is made up of a complex pore system that allows bacteria to thrive.AquaClear Power FiltersPower Filter MaintenanceFor maximum filter operation and efficiency, regular cleaning of the filter and its parts is recommended every two weeks.Always unplug the Aquaclear Power Filter prior to cleaning.First you want to remove the cover, filter basket, and discard water remaining in the filter case. Thoroughly rinse collected debris from the case, impeller cover and impeller assembly using clear lukewarm water.Then intake "U" tube and extension tube can be cleaned with a filter stem brush to remove any build-up of deposits.When all parts have been cleaned and thoroughly rinsed, reassemble filter and replace any scheduled media. Install the filter once again back on the aquarium making sure that the filter is tipped slightly forward.Then fill the AquaClear filter box with aquarium water. Finally plug the filter into an electrical outlet and the AquaClear will self-prime and begin running in a few seconds.Media ReplacementAquaClear Foam Filter Insert: Replace Foam Filter Insert every two months. AquaClear Activated Carbon Filter Insert: Replace Activated Carbon Insert every month. AquaClear BioMax Filter Insert: Replace BioMax Insert every three months.Warranty The AquaClear Power Filters are guaranteed against defects in material or workmanship under normal aquarium usages and service for as long as you own the filter.

Review: Great product - I’m really impressed with the Fluval 50 Power Filter. Within just a few hours of setting it up, my aquarium water went from cloudy to crystal clear. It runs quietly, is easy to install, and provides strong filtration without being too bulky. The build feels high quality and durable, and I like that the media compartments are customizable for different filtration needs. My fish are thriving, and the tank looks cleaner than ever. Definitely worth it if you want reliable, efficient filtration for your aquarium.
Review: GREAT FILTER! - I purchased an AquaClear 50 Power filter for my 29 gallon freshwater tank. This filter replaced an Aqua Tech 30-60 model which would not keep my water clear unless I replaced the cartridges every week (as you can imagine, that was getting ridiculously expensive). My fish kept looking sick and I eventually decided it was the filter not working right (I had an Aqua Tech 20-40 before and that one didn't work either; thought bigger filter is better but apparently not with that brand). Anyway, I installed this filter in the evening and at the time my fish were REALLY sick looking and I was of course checking on it often hoping it would work. The next morning the water was still cloudy and my fish weren't behaving much different, so I did a 10% water change (changing too much water + new filter = trouble). Ten percent really isn't much, so the water was still cloudy. I did notice that 24 hours after installing the filter, my fish began to look slightly better and a bit more active. Within 36 hours this filter made my tank water crystal clear! (See my product images for before & after shots.) I just purchased a 2nd Aqua Clear 50 because I do have a few messy fish in my tank and this filter only moves 200 gallons per hour - for a 29 gallon tank it should be moving about 230 gallons minimum. I didn't buy a larger model because I have only about 2.5" between the back of my tank and the wall. If you have that issue, here are the approximate measurements of the unit and how much space you need between tank and wall: AquaClear 20: 5"L X 4"W X 6"H with 2 1/2" of the width behind the tank AquaClear 50: 7"L X 4"W X 6 1/2"H with 2 1/2" of its width behind the tank AquaClear 70: 8 1/2"L X 6"W X 8"H with 3 3/4" of its width behind the tank AquaClear 110: 13 1/2"L X 6 3/4"W X 9"H with 4" of its width behind the tank Will try to update about longevity once I've had it a while. So far, minimal noise, easy to install, no problems! Fish are very active, they like it! Update (6/12): The first filter I got leaked by the cord. It did cause some water damage to my stand (wood). Thankfully my 29-gallon background was folded at the bottom and it caught most of the water in the fold. I contacted desertcart and they sent a replacement with 1-day shipping. My 2nd 50 filter worked while the first was being replaced so I was glad I had 2 to start out. Despite the leak, I still purchased more of these filters for another tank I set up and am not changing my 5-star rating. I really feel these are the best out there! One suggestion, though, be sure to place something behind your tank, under the filter in case it leaks, and check it regularly. I'm going to use a Rubbermaid container (with the lid off). I have not had problems with any of the other filters leaking, hopefully it was just that unit and not a common thing.

## Questions & Answers

**Q: Would the 110 be overkill for a 36 gal goldfish tank? Would the 100 work just as well?**
A: I run (2) 110's on a 90 gallon tank of exotic goldfish. That means I'm running 1000 gallons an hour through the filters on high. I've raised exotic goldfish for 50 years - goldfish are the DIRTIEST fish there are. They produce more ammonia than any other fish. These filters work great. I have some mini's - now called the 20's - which I have had for 35 + years, and they still run as well as the day I bought them. I ONLY USE AquaClear. Best filter out there! They last forever because there are no moving parts to break. There is only a magnetic impeller. In 50 years, I've only had to replace one intake tube that broke, and it was my fault! I tried a canister filter once, and quickly went back to my Hagen AquaClears. Easier to use, and as big as they are, you can use any kind of media in them that you want to use. You cannot go overkill on filtration for goldfish.

**Q: do you need to replace the filter media in time, and if so, how expensive is the whole kit**
A: I ditched the carbon early on, never clean the ceramic donut things and clean the sponge once every 6 months.  Have had it 2 years with zero issues and a very stable tank for fancy goldfish.   Love this filter.  Less maintenance and less noise than others.  I actually came here to purchase a second one for my tank to replace my old hang on the back filter.   So I will have two of these 60-110 gallon filters on my 55 gallon tank.   Sounds over kill but it’s not for them dirty goldfish lol.

**Q: Will the 110 fit on over the 1-1/4" tank edge of my 70 gal tank?**
A: 13 1/2"L X 6 3/4"W X 9"H with 4" of its width behind the tank.

**Q: How many Gallons of water per hour (GPH) does this filter handle?**
A: I am not sure, but I know it turns it over at least once per hour.  I can tell you I use it in a 100 gallon turtle tank (turtles are notoriously dirty) that is about 2/3 full.  It keeps the water sparkling clean and free of all debris all the time.  The water NEVER looks dirty.  I do clean the media and vacuum the tank once every 1 - 1 1/2 weeks, but I have been extremely pleased with this filter.  If it ever breaks, I will definitely get another.

### ⭐⭐⭐⭐⭐ The best HOB filter in my opinion
*by J***M on March 3, 2024*

I’ve bought just about every brand of HOB filter. Some lasted a few months, one came with a tank and was so noisy I tossed it and then there are the aquaclear filters - as far as I’m concerned, they are the only HOB filter I’ll buy for a 5 gallon and above tank and here’s why: 1. They are easy to get started 2. Super easy to find accessories if you want a baffle to control the flow speed or a filter end cover to protect tiny fish or shrimp from being sucked up 3. Quiet - yea you heard me - these are quiet! 4. You can use whatever media you want. You don’t have to buy their cartridges. This is huge in the longer run 5. They keep running Ok so that’s my perspective as someone who has purchased other name brands and had to toss some almost immediately, others a few months in. These just keep running. One note: buy up a size - if it says 10-30 gallons, and the next size says 30 - 50 gallons and you have a 30 gallon tank. Get the bigger one. You will have less water issues with better filtration. Now I am an over-filterer… I usually run a HOB and a sponge filter. For sponges I like a few brands - but this review is about the aquaclear. I don’t need to use a sponge filter but I like to over filter. On big tanks (I’m a weenie in aquarium terms- when I say big for me that’s 75 gallons) I will use a HOB and a sponge and a canister. (Yes - I am an admitted over filterer) - and yes I change my water by 10-25% every week on smaller tanks (30 gallons and under. And every other week on my big tanks - up to 75 gallons). Unless my water tests (using the actual API water test - not strips) show I need to take action. I tend to heavily plant my tanks and I don’t overstock with fish or shrimp. I figure I’ll do what I can to keep fish alive since they have no control. Anywho - buy one of these if you are looking for a steady Eddie HOB that will keep working and not cost you and arm or leg to replace media over time. (Not that I change media that often since that’s where most the beneficial bacteria live anyway) Note: My water tends to be a bit brown as I use a bunch of leaves and other botanicals to keep my fish and shrimp healthy and happy. It works!
