The Reefdoser can automate many tasks in your aquarium system: - regular dispensing of trace elements and fertilizers into salt and freshwater systems - controlled addition of two part calcium additives in separate intervals - accurate dosing of Kalkwasser into reef tanks - regular feedings of live phytoplankton and zooplankton

Tips

  • Use to dose two part calcium solutions, with the ability to separate the A & B doses with an appropriate time lapse to ensure they don`t interact within the sump volume.
  • Use to automate trace element additions to ensure exact dosages, added steadily over your desired time interval.
  • Use for regular plankton feedings from your Plankton Reactor or Plankton Light Reactor to keep a steady supply of live food available for your filter feeding invertebrates.
  • Using the included one-way check valve (always on the suction side) ensures positive progress of the fluid through the dosing line while eliminating back-siphoning.
  • Replace the persitaltic tube periodically, depending on severity of duty, to maintain performance.

    “Don't buy this”
    1.0

    One of the most attractive dosers. A lot of people seem to hate the programing method for this dosers because it is not the norm, I love the programing method of it, I can dose every second, minute, hour , day or week if I chose to, simply by telling it dose x amount every 2 hours or 36 hours or 48 ...Read More

    “Reef Doser”
    3.0

    I like this product well enough. If you want something to run in the middle of the night, you have to stay up until the middle of the night to start it since it doesn't use the clock, but uses intervals of time. I had to do this because one of the pumps is not air tight. So I have to fix this.

    “good, but WARNING!!!”
    3.0

    The pumping mechanism is great and works perfectly, even for tiny doses (like 1 drop). HOWEVER, I have a big problem with the design...the programming is ridiculous, I'm not even sure I want to keep the thing. It only allows you to program in "cycles," not by a clock. In other words, y...Read More

    “Great, but use check valve!”
    4.0

    I was ready to return this unit as useless until I finally noticed the Tips and Tricks section of the product page here on Marine Depot! The manual doesn't tell you this: If you install the pump where it is above your source, you MUST use a check valve on the INPUT side (the manual shows the ch...Read More

    “what else do I need?”
    1.0

    The product does not ship ready to use. I need to purchase tubing and manufacture some sort of bottle-hose connector in order to put the thing to use. Also, the directions are confusing and don't provide any dosing time to amount of dosing information. This is a product of Poland and the english ...Read More

    “Dosing Pump”
    5.0

    The aqua medic works extremely well when setup properly. Instructions are not the best but they have a help number which is useful. Can program pumps individually and deliver the volume based on elapsed time since pump is of one speed. In power failures you must restart but program remins intact in ...Read More

    “TOO COMPLICATED 4 $”
    3.0

    Mechanically it operates fine but the ease of understanding the display, programming and resetting the time cycles could be much better. Using it feels like I am an unqualified layman using a device specifically designed for and to be used by experts. It's not very consumer-friendly. When I press...Read More
