Description
Automated Feeding. Real Frozen Food.
The aF4 is the world's first and only automated frozen fish food feeder — a patented system refined over five years of development to deliver consistent, controlled feeding using genuine frozen food. Built for both saltwater and freshwater aquariums, it replaces unreliable timers and manual feeding with precision automation.
Now Standard Equipment Every aF4 now ships with the upgraded High Flow Cup included at no additional cost — our redesigned reservoir engineered to eliminate flow restrictions, improve feeding consistency, and simplify feed-tube and temperature-probe placement.
Core Technology
RSW Cooling Technology Using Refrigerated Salt Water (RSW) cooling, the aF4 keeps frozen food in liquid form and fresh for up to 21 days — no daily handling required.
Self-Cleaning System The aF4 rinses its feeding tubes between every feed and includes a full deep-clean function, keeping the system clean and dependable over the long term.
Precision Feeding Dial in exact portions from 5mL to 50mL per feed, and dispense food up to 6 feet from the aquarium.
Power Interruption Resume If power is lost, the aF4 resumes where it left off — protecting food from spoilage and keeping feeds on schedule.
Disclaimer: The aF4 ships with 6' (183 cm) of feed tubing. Approximately 6" (15 cm) routes internally, leaving roughly 5'6" (168 cm) of usable external reach.
Built for Your Setup
Versatile Mounting Compatible with rimless and euro-braced aquariums using the included Multi Aquarium Mount. Rimmed aquariums are supported with our Rimmed Aquarium Adapter (sold separately).
Smart Controller Compatible An onboard 0-10v interface integrates the aF4 with smart controllers such as the Neptune Apex, GHL Profilux, or Hydros.
Effortless Maintenance The removable reservoir makes cleaning and food prep simple, and a dedicated condensation drawer keeps moisture under control.

Quality products. Essential equipment for marine reefing. Great set up help for holiday away from home. But the con is expensive postage for oversea shipping.

No Stress during Long Weekend
The tank we have is needing more than 1 feed a day now so with a long weekend looming and no one we know locally we decided to invest in the af4. Ordered Sunday, delivered Thursday across the pond-wow.Trained ourselves with your videos and came back to a thriving tank. Great product thanks.

Game Changer!
So far seems to be working perfectly. In terms of freedom and flexibility potentially a game changer for me and the family. Appears to be robust with fail safes - I’m controlling with Apex, and was easy to setup
