Hagen Fluval G Series Mechanical Pre-Filter Media
The mechanical pre-filter is housed in a cartridge which is directly accessible from the top of the filter. It can be cleaned or replaced without the laborious chore of disassembling the whole filter. Fluval has replaced the traditional mechanical filtration foam with a compact high capacity pleated cartridge that traps significantly more suspended debris in fresh or marine aquariums.
- Designed as a "no by-pass" system, debris remains caught between each pleat until it is removed and rinsed
- Routine cleaning of the cartridge will prevent solid wastes from breaking down and contributing to elevated phosphate and nitrate levels
- Tank will have clearer water and less solubilized wastes
