ReefDose is designed and built specifically for the daily supplementing of reef aquariums.ReefDose uses bespoke (patent-pending) single-drop-accuracy dosing heads together with an advanced controller that provides a full suite of features.

The “Dynamic Dosing Queue” run by the controller combines the desired dosing plans for each head into one coordinated daily dosing schedule for the complete device. The queue is automatically updated after any settings changes, and reschedules any doses that are missed due to unscheduled events such as power outages.

With programming through the ReefBeat App, ReefDose offers multiple options for fully automated, easy-set dosing, or a simple schedule of individually planned doses.

In addition to the regular flow rate, you can select the “Whisper” mode for almost silent operation, or “Turbo” mode if you want to get the dosing done as quickly as possible.

The ReefDose is part of Red Sea’s ReefBeat smart ecosystem, seamlessly integrating with all other ReefBeat devices.

Features:

  • Single drop accuracy dosing heads with a direct-drive planetary gear-motor, provides an accuracy of ± 0.05ml or an average deviation of 0.5% (over 10ml).
  • 4 easy-set, smart dosing options for each head, that are automatically combined into one coordinated schedule for the complete device.
  • Easy assembly click-on/off dosing heads (no tools or alignment required).
  • Automatic delay between the heads to prevent chemical interaction between supplements.
  • Daily dose per head of 0.2ml up to 1000ml in increments of 0.1ml.
  • On-demand manual dosing.
  • Secured connectors for flexible tubing: OD 5mm – ID 3mm.
  • 3 dosing flow rates: Whisper 15ml/min, Regular 30ml/min, Turbo 45 ml/min.
  • Motor life expectancy of 10 years – based on 250ml/day/head.

ReefDose 4 Dimensions: 22.5cm x 8.5cm x 8.5cm, wall mount bracket included.

Light, retro watch
Color: Brown/Brown/Natural
This is a light, comfortable and retro-stylish watch. A mixture of plastic, canvas, and faux-leather makes a good match for a college professor's tweed jacket with leather shoulders and elbow patches. It looks and feels cheap but it's actually a pretty good watch. Mine has a high contrast face making it easy to read. The hands have lume on them but it only glows for a few minutes. There is an indiglo feature when you press the winder so that's great. The day window is tiny and almost unreadable even with reading classes but other than that it is very functional. You can adjust the time and day independently (so you don't have to wind through 100+ hours to get the right day displayed). The winder setting to select between time and day adjust is very finicky. Fortunately you only need to adjust the day 5 times a year. The weakest part is the build quality. I'm not expecting Rolex, but the case corrodes really badly and the strap is short and the stitching failed so it fell off my wrist in about 6 months. I replaced the strap with a better one but the case corroded so badly I tossed it within a year. Other than looking cheap, poor build quality, and being thicker than I would like, I think this is a good watch.

A nice, comfortable watch.
Color: Black/ Green
A nice inexpensive everyday watch. It is accurate, a nice size for my wrists. You barely feel it as it is so light. it has a nice clear face Andy only gripe is that I wished it had slightly better loom. Other than that it is a great watch for the money and this is coming from someone with 30+ watches in my collection in all price ranges. It has earned its way into my regular watch rotation.

Good Watch for use in water.
Color: Black/ Green
Here's the deal. It's an excellent plastic watch. If you don't abuse it, it should last years. The advantage of metal bodies and crystal faces, is that they're lot more resistant to scratches compared to plastic, BUT they weigh a lot more than plastic watches. I love the size of this watch while at the same time, it surprisingly light on the wrist. Therefore it doesn't move all around like a heavy steel watch. I hardly know Im wearing this plastic watch. Also, I went snorkling offshore for a week with this watch, no leaks, no problems. It will stand up to water fine. So, if you don't abuse it, its a pleasure to wear, lightweight, waterproof, doesnt slip around, looks good. I imagine the battery should last 3-5 yrs like my last plastic quartz watch. For the price, its a very good watch.
