    Mini Fridge + Dosing Pump = Azoox Continuous Feeder

    As Azooxanthellate (“Azoox”) corals become more and more popular, so will automated feeding systems such as this. This regrigerated dosing set up was put together by Michael Lucazyn for his stunning Non-Photosynthetic Reef. Mike’s continuious feeder was inspired by Steve Weast’s set up, with a bit of insight from Matt Wandell on the venturi.

    In this set up, a programable dosing pump adds specified quantities of perishable reef foods within a small refrigerator. They are then dosed and simultaneously sucked into the flow via the venturi injector. As water flows through the fridge (and the venturi injector), the food is added directly to the aquarium. Simple, effective, and much appreciated by filter feeding animals.

    The biggest downside of this type of set up is cost and space. If you don’t like the idea of a mini fridge next to your tank, there is also the equally expensive GroTech Phyto Reactor–which with some creativity could by DIY’d.

    Mike recently switched to this venturi design, from a previous straight through design shown above. You can also catch a glimpse of Mike’s feeding regimen which includes: Oyster Feast, Roti Feast and Shellfish Diet. Captive Dendeonepthyas around the world just perked up at the mention of that triumverate.

      Why the venturi instead of piping straight in?

    • AdamMullins

      Nicely executed. Id guess the venturi would be more conducive to sucking the phyto down, where piping straight in would place extra backpressure on the dosing pump.
      What are the dosing rates? and are each in equal ratios?

    • http://twitter.com/MLukaczyn mlukaczyn

      The dosing rates are:

      6 ml daily of Shellfish Diet (1ml every 4 hrs)
      12 ml daily of OysterFeast (1ml every 2 hrs)
      20 ml daily of Rotifeast (.83ml every hour)

      With the old set up with the Tee’s; if you remove one of the lines, water would spray out like a fountain from them. By putting the venturi inline, it will only suck air in and no water comes out. This is the fail safe if the line coming out of the doser would break or come undone my tank would not drain out onto the floor.

      Looks nice mike

      “there is also the equally expensive GroTech Phyto Reactor”
      ???
      The phyto reactor will cost 1400+, the fridge will be 60+ 300 for dosing pump + lets say 40 for plumbing for a total of around 400, a lot less than the 1400.

      Joost, this statement was for comparison purposes. DIY to off the shelf is never an even comparison.

      That said, the 11L PhytoBreed roughly a year ago a few PhytoBreeds came in landed at $600 USD–without their automated dosing pump. Typically they retail for €520.
