Aqua Illumination Axis 90 Centrifugal Pump

Description

Aqua Illumination Axis 90 Centrifugal Pump — Controllable 3,500 L/h DC Return Pump for Larger Reef Systems

A 340 L reef with a sump under the stand wants roughly ten turnovers an hour through the return, and that is where the largest Axis sits. Aqua Illumination Axis 90 Centrifugal Pump (SKU: HYAX90) is a submersible DC return pump delivering about 3,500 L/h with a maximum head of around 3 m from a variable 40 W, which AI recommends as a return for larger aquariums up to about 340 L. The body measures 74 mm across and 197 mm tall, and the two barbed nozzles supplied, 20 mm and 25 mm, match the return lines found on most sumped reef tanks in that size class.

Like its smaller siblings it carries an integrated driver on the cord, run from the button or from the myAI or Mobius app, and from a Neptune Apex through the MXM module. A schedule varies flow across the day, feed mode drops the pump to a crawl for ten minutes so food stays in the display, and calibration sets the working range; in a back-siphon the motor keeps turning without moving water. Two to five seconds on the button enters feed mode, six seconds turns it off. It also suits large reactors and UV units; only the pump body is waterproof, and the teal feet must be fitted.

Usage & Application

When to Use

• Sumped reefs to 340 L: A return pump with the head for a tall stand.
• High-flow returns: Systems wanting close to ten turnovers an hour.
• Large reactors and UV: Adjustable flow for calcium reactors and big sterilisers.
• Controlled feeding: Reefs that slow the return while corals are fed.

Installation & Setup Guide

• Fit the feet: The teal rubber feet are essential for flow, not optional.
• Nozzle: Choose 20 mm or 25 mm and connect the return hose or pipe.
• Submerge: Sit the pump in the return chamber with the driver and adapter dry.
• Configure: Pair in myAI, calibrate min and max, schedule flow and set feed pauses.
