The HOB (Hang on bracket ) allows easy fitting of a D4 roller filter, or Drop-in UV, it can also act as a filter sock holder for use when cleaning of the sump

The Drop-in filter then automatically unrolls new material as it gets clogged, removing suspended particles from your aquarium and producing crystal clear water.  Enjoy maintenance-free aquarium filtration for months at a time.

The Drop-in filter is a direct replacement for filter socks on sumps with sock trays. Simply remove your sock and insert the Drop-in Filter.  As water passes through the Drop-in filter and the filtering material becomes saturated with waste, the water level will begin to rise.  When water contacts the optical sensor, a motor is activated to advance clean filter material. As clean material is exposed, water is now able to flow freely, lowering the water level in the sock tray and deactivating the motor.

1. Results in crystal clear water filtered down to 50-microns — double the filtering capacity of most filter-socks.
2. Waste is removed from the water column before it has time to breakdown, helping to maintain low nutrient levels.
3. The constant chore of monitoring and swapping filter socks or other mechanical media every few days is eliminated for months at a time. Once the filtering media is exhausted, replacing the roll is very simple.
4. Fitting the unit to a sump with filter socks requires no adjustment simply remove the sock and fit the unit, other mounting options are available for sumps without sock holders.
5. Multiple units can be ran side by side and work in tandem.
