Storing the slurry at 1-2C with RO water versus 0 to -1C with saltwater reduces the duration the unit can operate before the food begins to spoil from 20 days down to about 12 days making it safe for freshwater aquarium applications and users can specify the temp they would like the unit to operate at from -2C to 5C. The refrigerated salt water tech enables the slurry to be stored at or below 0C without the slurry freezing solid. Instead of advancing a crude carousel to simply drop frozen food in the tank water the Automatic Frozen Fish Food Feeder uses Refrigerated Salt Water (RSW) technology which allows fresh fish food slurry to be dispensed for up to 20 days, for a total of about 14 typical cubes of frozen food. The sleek new enclosure of the Automatic Frozen Fish Food Feeder has a remote touchscreen for controlling, programming and monitoring the actions of the feedings but the real change and innovation is how the Automatic Frozen Fish Food Feeder actually works. The most recent renderings of the InD aF4 looks more like a nano chiller that sits next to or below your tank and now it injects food to your tank from up to six feet away.

This company and its device first hit our ‘new reef tech’ radar way back in 2019 when it wasn’t much more than a food dispenser with a chiller strapped to it but the latest, and hopefully final, iteration is a completely different animal. The Automatic Frozen Fish Food Feeder (AF4) by InD Creations is a radical aquarium device which is slowly moving further away from a concept and inching ever closer to reality.
