DOSUKA multi-purpose dosing and fluid delivery system of uncompromising quality combined with the simplicity of Apex Fusion software wizards for operations such as:
2-part dosing (Calcium and Alkalinity)
Other additives dosing
Automatic water changes
micro-quantity dosing
delivery of liquid foods and supplements
So, here’s what the DŌS can do
The DŌS is a multi-purpose Dosing and Fluid Metering System. The DŌS connects to any Apex via its AquaBus connection. The true versatility and functionality of the DŌS comes to life via the software wizards built into Apex Fusion. This takes dosing to a whole new level in terms of ease of use as well as functionality when compared to standalone dosing systems because the DŌS is part of your Apex ecosystem. Not only can you integrate it into other operations and devices you have configured, but we also will be continuing to expand on its capabilities as time goes on via software updates to Apex Fusion.
2-part dosing made easy
The #1 reason people purchase a dosing system for their aquariums is for consistent and easy dosing of 2-part solutions (calcium and alkalinity) to their reef tanks. The most common method for doing this today is to use standalone dosing pumps and run them on a timer using seconds or minutes to determine how much to dose. This is not only confusing, but also prone to inaccuracy. Everyone knows that when measuring a fluid it is done by volume, not time. Every dosing calculators out there uses volume. So, with the DŌS (and the Apex Fusion interface) you simply enter the amount you want of each part of the additives (one on each pump) and what hours of the day you want it delivered. The DŌS then sets up all the dosing intervals within that time period. When that time interval is finished, the exact volume you set has been delivered. It even automatically chooses the slowest speed necessary for the pump so that it minimizes noise.
Water changes – the never ending chore of an aquarium
Hate doing water changes? – everyone does – so they never get done as often as they should. Not only that, water changes are disruptive to the stability of your system since all of that change is happening at once.
With the DŌS all you do is place your empty vessel and your fresh stock of saltwater under your stand. Then, with the Apex Fusion wizard just tell it amount of water you want to change over what length of time and the hours of the day you want it to happen and it figures it all out for you. It will perform an automatic, continuous water change for you. It gets better. If you have our dual optical water sensing accessory Apex Fusion will send you an email or text message letting you know it is time to change out the jugs. Less time pumping, siphoning, and sloshing water and more time enjoying a great aquarium.

It works well.
Size: 8 Fl Oz (Pack of 1)
Great product that delivers on what it says it does. This won’t fix a mechanical problem or damaged component, but it will fix a stuck float, varnished tank, gummed up jet, or partially blocked emulsion tube.

It Works
Size: 8 Fl Oz (Pack of 2)
This stuff works. I added it to my four 5 gallon gas cans before filling them up. I’ve used 10 gallons of gas in my lawn tractor so far and can tell it likes it. I do annual maintenance before summer and check or change the spark plug so it performs the best it can. I have 508 hours on it and with this it seems like it idols smoother, which indicates it has helped in the carburetor since I haven’t had to remove it and clean it. Works great.

Great product
Size: 4 Fl Oz (Pack of 1)
Used this stabil in my rider after first start of the season. Machine running rough and uneven. Drained old fuel and added it. Within 15 minutes at full throttle it began to run normal. No back fires and engine back to normal. There will always be a bottle of this in my garage.

Works Great
Size: 8 Fl Oz (Pack of 1)
I"ve used Stabil gas treaments for year but never this particular type. With gas the way it is, I decided to see how it might help my mower and also my older truck. My older push mower which admittedly doesn't get pampered and petted seems to love it. Either it's grateful to get anything special or this stuff really has helped. The first tank seemed a little smoother but by the second I could hear the difference and feel it with the smoother sound and seems more power. It's easy to mix and use and Stabil is a well known reputable company.

Easy and worked seamlessly with the new Apple MacBook Pro
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
This was our first (Apple MacBook Pro M4) and big purchase directly on Amazon. I was not concerned about the order and product, but more concerned about the AppleCare+ not being connected directly to the device (after reading some reviews). However, I am happy to report that this was the first thing I checked as soon as we set up our computer. We are set for 3 years ... so thank you, Amazon and Apple, for working out the backend stuff and making our lives easier. It worked for us. It was easy, and I am happy with the overall quality of the process. Oh, don't forget it was cheaper than buying yearly from Apple directly.
