Filter- Aqueon Quiet Flow 75

Featured is a LED filter cartridge change indicator light that flashes when the cartridge becomes clogged with debris, providing a reminder that it's time to replace the cartridge. A great benefit of the Aqueon QuietFlow® filters is the internal pump design that helps dampen noise, eliminates leaks and is self-priming, meaning it starts up automatically after cleaning or power interruptions. Higher flow rates also ensure a higher dissolved oxygen content for healthier, more active fish. There are five total stages of filtration-mechanical, chemical, biological and an additional specialty pad-for the cleanest, clearest, healthiest water.

Stage 1 - Dense floss removes particles and debris.
Stage 2 - Activated carbon removes toxins, odors and discoloration.
Stage 3 - Patented Bio-Holster provides surface area for beneficial bacteria that remove toxic ammonia and nitrites.
Stage 4 - Bio-Media grid supports additional beneficial bacteria establishment while adding more oxygen. It also reduces splashing making the return exceptionally quiet.
Stage 5 - Specialty filter pad option for additional carbon, ammonia reducer or phosphate remover.
All filters use Aqueon Replacement Filter Cartridges and Aqueon Specialty Filter Pads. QuietFlow® LED Pro 10 - Medium cartridge. QuietFlow LED Pro 20, 30 and 50 - Large cartridge. QuietFlow® LED Pro 75 - two Large cartridges.
