The AquaMaxx HF-M filtration system is designed to be the complete filtration system for your saltwater fish or reef aquarium. The simple hang-on back design allows you to hang the filtration system on any aquarium ranging from 20 gallons to 60 gallons. The HF-M is also designed to be customizable so you can add additional chemical, biological or mechanical filtration to match the requirements for your aquarium.

The AquaMaxx HF-M includes an efficient protein skimmer. Using the same Shark 1.0 needlewheel pump (modified Italian-Made Sicce) as the popular HOB-1, the HM-F efficiently removes dirty protein from your aquarium before it breaks down into ammonia, nitrate and phosphates.

After the protein skimmer stage, water then passes through a second filtration stage. A filtration cartridge is included and can be filled with mechanical media (such as filter floss), biological media (such as ceramic rings or SeaChem Matrix) or chemical media (such as activated carbon or AquaMaxx AIO media).

Water then passes though a third and final chamber where additional filters can be added. The third chamber of the HF-M is designed to accommodate up to two AquaMaxx FR-S media reactors (sold separately): which can be used for carbon and/or GFO. If additional chemical filtration is not required, the chambers can be used as a refugium for additional nutrient reduction and to culture live foods for your reef aquarium.

The HF-M also features a built-in probe holder (for up to 3 probes), a dosing tube holder and cut-outs on the lid to run your cords and tubes though. The well-throughout design eliminates all the clutter and keeps your aquarium looking clean and sleek.
