If you’ve been keeping fish for any time, you’ve heard of AquaClear filters.
They’ve been around for quite a while, and many consider them the best HOB filters because they’re quiet, efficient, reliable, and work great.
- Aquarium filtration system that offers superior contact time with filter media and energy efficient pump lowers operating costs
- Quick and easy installation; we recommend that you clean aquarium filter every 2 weeks for maximum operation and efficiency
- Provides optimal mechanical; chemical; and biological filtration
- Comes equipped with AquaClear Foam; Activated Carbon Filter and BioMax and Cycle Guard for superior water quality

The AquaClear brand is owned by Hagen, which also owns the famous filter brand Fluval.
With that kind of pedigree, this company produces quality aquarium products, and AquaClear filters are no different.
In this review, we closely examine the AquaClear 70 HOB Filter and whether this truly is the best HOB filter for your tank.
Let’s start with our experience using this filter.
Contents
Our Experience & Hands-On Evaluation
First, everything you need to set up this filter is in the box, including filtration media.
It comes with AquaClear Foam, Activated Carbon, BioMax, and Cycle Guard.
This media provides three stages of filtration (mechanical, chemical, and biological).
The media container on this thing is enormous.
Most HOB aquarium filters have media trays, but the AquaClear 70 filter has an open container instead.
This lets you use a ton of media for better filtration and experiment with your media mixture.
The flexibility you have with this is a huge selling point.
The overall build quality is solid.
Of course, it’s made of plastic, but the materials are on par with what you’ll find in most filters.
Durability should not be an issue; many people keep these running for years.
The filter operation is whisper-quiet, but we did notice a slight rattle from the lid shaking against the top of the filter.
This is a quick fix if you’re concerned about noise.
You can keep the lid off entirely or place a weight on it.
We put our fish food container on the cover, solving the problem.
Maintenance
The AquaClear 70 is one of the most straightforward filters to clean.
- All you need to do is unplug it and remove the filtration media.
- You can then rinse all of the media off in old aquarium water. Then clean the filter box and intake tubes using a pipe cleaner.
- BioMax and Cycle Guard should be replaced every 3-4 months, while Activated Carbon can be replaced monthly.
- AquaClear Foam can last up to 6 months before needing to be replaced.
- You should also open up the impeller chamber and pull out the impeller, clean the blades and the magnet, then reinsert it into the box.
The Filter Inserts
The AquaClear filter comes with four filter inserts: AquaClear Foam, Activated Carbon, BioMax, and Cycle Guard.
- The AquaClear Foam insert is a mechanical filter that catches large particles and debris.
- The Activated Carbon insert removes toxins, odors, and discoloration from the water.
- The BioMax insert is a biological filter that contains beneficial bacteria that break down ammonia and nitrite.
- The Cycle Guard insert helps to keep the beneficial bacteria healthy and active.
Can I use my media?
Yes, you can use your media in the AquaClear 70. The filter container is spacious and allows for various media types, and one of the main reasons this filter is so customizable to your needs.
Replacement Parts
The impeller and the blades are the most common parts that need to be replaced on the AquaClear filter.
The impeller is the rotating blade that draws water into the filter from the tank.
The blades are attached to the impeller and help to move the water.
The impeller or blades must be replaced if they start to wear down.
It is essential to replace these parts regularly to keep the filter running at its best.
AquaClear offers replacement impellers and blades for all of their filters, and you can buy them right in your local fish store or on Amazon.

What You Need To Know?
AquaClear filters are very well-known and highly recommended in the fishkeeping community.
They provide excellent filtration, nearly silent operation, and legendary durability.
People regularly run these things for years without any problems.
Although the AquaClear is a HOB aquarium filter, it uses a bottom-up design usually only found in canister filters.
This means the water rises from the bottom of the filter rather than trickling from the top down.
It also has a huge filter container much more extensive than you’ll find in other HOB filters, allowing you to customize your mix of media and pack it in for optimum filtration.
There must be somewhere for the water to go with this design, but through the filtration media.
This filter also has a patented refiltration system that increases contact time by cycling the water back through the filtration media. As a result, the highly efficient pump has a high flow rate and low energy consumption.
Dimensions:
The approximate dimensions of the AquaClear 70 are 9.8 x 6.7 x 9.8 inches.
Specifications:
- The filter is rated for aquariums with up to 70 gallons of water capacity.
- This can be increased depending on how much media you place in the chamber.
- Two chambers hold plenty of media for easy replacing and customizing (i.e.) Carbon, bio max, etc.
- The filter has a high flow rate of 300 gph and low energy consumption.
- The AquaClear 70 is a powerful and efficient HOB filter that can handle tanks up to 70 gallons in size.
Priming:
Priming the AquaClear 70 is easy—all you need to do is fill the filter with water and plug it in.
Once the water is turned on, the filter automatically primes itself.
There are a few things to keep in mind when priming an AquaClear filter:
First, ensure the filter is completely submerged in water before turning it on.
If the filter still isn’t priming correctly after a few tries, unplug it and let it soak in water for a while. Then try priming it again.
Sometimes putting pressure on the intake tube helps suck the water into the filter box a little easier.
Sizes Are Available?
The AquaClear 70 is part of Hagen’s AquaClear line of filters that includes:
- AquaClear 10: Up to 10-gallon tanks, 80 gph flow rate
- AquaClear 20: For 5-20 gallon tanks, 100 gph flow rate
- AquaClear 30: For 10-30 gallon tanks, 150 gph flow rate
- AquaClear 50: For 20-50 gallon tanks, 200 gph flow rate
- AquaClear 70: For 40-70 gallon tanks, 300 gph flow rate
- AquaClear 110: For 60-110 gallon tanks, 500 gph flow rate
All filters in the AquaClear line offer the same features and benefits, just for different-sized tanks.
However, we recommend getting the higher model for your tank to ensure the most efficient filtration.
For example;
The AC50 and AC70 would work for a 50-gallon tank, but we recommend using the larger AC70 for greater capacity.
