A great benefit of the Aqueon QuietFlow filters is the internal pump design that helps dampen noise, eliminates leaks and because it is self-priming, 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.
