Complete hang-on saltwater aquarium filtration system for up to 60 gallons. Great for reef tanks or fish-only tanks!

The JNS 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 JNS HF-M includes an efficient protein skimmer. Using the same Shark 1.0 needlewheel pump 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 chemical media (such as activated carbon ).

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 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.
