Product Specifications & Highlights
Key Features
-
High Flow Volume: 757 LPH flow rate ensures thorough water turnover. It has a precision motor design, while its re-engineered rotor configuration enables smoother rotations, reduced vibration and quieter operation (AC20/AC30/AC50/AC70 models only).
- 4-stage filtration: A newly calibrated water path cycles through 4 complete filtration stages to optimise cleaning performance, providing superior water clarity and quality.
-
Gentle Re-Filtration System: Re-circulates water through media when flow is turned down for deeper filtration. By allowing 1 of the 3 media inserts to be changed at a time, it supports continuous and effective biological filtration without harmful fluctuations.
- CycleGuard beneficial bacteria support: CycleGuard maintains your aquarium’s biological balance by providing beneficial bacteria support, which prevents nitrogen cycle disruptions. Filter-to-tank stepped interface – self-levelling in most cases for convenient installation. Prevents water spills (AC20/AC30/AC50/AC70 models only).
-
Quiet, Reliable Motor: Energy-efficient impeller unit operates with minimal noise; its sound-dampening cover minimises the eco chamber effect. Its patented refiltration system has a unique feature that permits flow rate adjustment without compromising filtration efficiency. When flow is reduced, the system will process up to 50% of the water several times, ensuring exceptionally clear water.
-
Includes Full Media Kit: Comes packed with original AquaClear Foam, Carbon, and BioMax media. Redesigned easy-access media basket and all-new intake sponge.
