AquaClear 110 Power Filter, Fish Tank Filter for 60- to 110-Gallon Aquariums Review (2026)

Who the AquaClear 110 is built for

This filter is aimed at owners of large aquariums, 60 to 110 gallons, who want strong mechanical, chemical and biological filtration without running hoses and a canister under the stand. It suits a hobbyist who values easy access for maintenance, since the media basket lifts straight out from the top rather than requiring a canister to be opened and bled of air. It is a good match for community and lightly planted large tanks where filtration capacity matters more than a hidden equipment footprint. It fits less well on a heavily scaped display tank where every visible piece of hardware detracts from the aquascape, since the filter body and intake tube sit in plain view at the back of the tank.

Flow rate, media and how it filters

The AquaClear 110 is rated for aquariums between 60 and 110 gallons and can move up to about 500 gallons per hour at its maximum setting, with a patented flow control dial that can be turned down to roughly 166 gallons per hour for gentler flow. The media basket accepts foam, activated carbon and BioMax biological media, and the basket's open design lets an owner stack or substitute media in almost any order or combination, which is more flexible than filters with fixed cartridge slots. This gives it mechanical, chemical and biological filtration in one hang-on-back unit, closer to canister-level capacity than most other HOB filters offer.

Living with a large HOB filter

Because there is no canister and no hose routing beneath the stand, maintenance is quicker: lift the lid, pull the basket, rinse or replace media, and reseat it, all without disconnecting tubing or bleeding air from a sealed unit. The tradeoff is that the filter body sits behind the tank and needs clearance from the wall, and the intake tube and output are visible inside the tank rather than hidden below like a canister's spray bar can sometimes be arranged. The adjustable flow dial is useful for tuning turnover without buying a smaller model, which matters if stocking or plant load changes over time.

How it compares with other hang-on-back filters

Against the smaller AquaClear 20, which scores higher in this same guide for tanks up to 20 gallons, the 110 is simply built for a much bigger aquarium and the two do not overlap in use case. Compared with the Marineland Penguin 450 and Aqueon QuietFlow 50, both rated for smaller tanks up to 50 to 90 gallons, the AquaClear 110's open media basket gives more flexibility than Marineland's fixed cartridge and BIO-Wheel design or Aqueon's proprietary filter pads. The main cost of that flexibility and capacity is the visible bulk of the unit on the back of the tank.

Verdict and who should choose differently

The AquaClear 110 earns our score of 8 out of 10 as a strong, flexible hang-on-back option for large aquariums that need real filtration capacity without a canister setup. It is the right call for a big community or lightly planted tank where maintenance ease and media flexibility matter more than a hidden equipment profile. Anyone building a heavily scaped display where visible hardware breaks the composition should look at a canister filter or a sump instead. For a straightforward, powerful HOB on a 60 to 110 gallon tank, this filter remains one of the more capable choices in its class.
