What You Need To Know About The AquaClear 70
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 an HOB aquarium filter, it uses a bottom-up design usually only found in canister filters. This means the water rises up from the bottom of the filter, rather than trickling from the top down.
It also has a huge filter container that is much larger than what you’ll find in other HOB filters, which allows you to customize your own mix of media and really pack it in for optimum filtration.
With this design, there’s nowhere for the water to go 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. The highly efficient pump has a high flow rate and low energy consumption.
All filters in the AquaClear line offer the same features and benefits, just for different sized tanks. To ensure the most efficient filtration, we recommend getting the higher model for your tank.
Both the AC50 and AC70 would work for a 50-gallon tank, but we would recommend going with the larger AC70 for greater capacity.
Can hold huge amounts of filtration media compared to other filters.
Large filtration volume allows you to mix and match media.
Dead silent and efficient operation, so you can rest easy.
Provides excellent filtration capabilities.
Comes highly recommended by many owners, so you know it works.
Instructions are not the greatest, but with YouTube this is no problem at all.
Debris can get trapped in propeller box and will need to be cleaned out.
The lid may rattle a little bit, but this is easily fixed.
AquaClear media bags are a tad pricey, but you can easily use your own media.

Hands On AquaClear 70 HOB Filter
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.
All of 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 allows you to use a ton of media for better filtration and lets you experiment with your media mixture. The flexibility you have with this is a huge selling point.
The overall build quality is solid. It’s definitely made of plastic, but but the materials are on par with what you’ll find in most filters. Durability should not be an issue, and 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 either keep the lid off completely, or place a weight on top of it. We ended up putting our fish food container on top of the lid and it solved the problem.
