The Aquavitrol Sentia® Dose Modular Aquarium Dosing system, you can take control of your liquid supplement dosing into your aquarium. To operate this system, you need a Primary Control Unit (sold separately) and then you can add an unlimited number of Secondary Units (sold here) to the Primary Control Unit.

KEY NOTICE: To operate this system you MUST separately purchase a Primary Control Unit (you can connect as many Secondary Units as you want to a single Primary Control Unit).

You can add colored rings to each Secondary Unit to identify the supplement. The head of each Secondary Unit can be rotated to allow you to mount as desired and/or direct the tubes in any desired direction.

The Sentia® Dose units are slim and with a sleek well-engineered look allowing you to leave them out and they will look great.

With the Sentia® app, you can control the Sentia® dose modular doser. Manage multiple aquariums and devices. View statistics like reservoir levels, upcoming doses and scheduled water tests at a glance. Receive alerts and reminders, and review dosing logs to keep you in control of your dosing regimen. Automatically create suggested dosing schedules or create your own with complete versatility of days of the week, time of day, doses per day, total volume, and volume per dose.

In addition to the ability to manually dose using the pump itself, you can do an Instant Dose using the app at any time. The real advantages come from the versatility in scheduling and the four different dosing modes that allow you to more easily dial in the correct doses and best schedule for your system.

In addition, the Sentia® Dose takes a lot of the headache out of figuring out dosing levels. For example, assume you do a water test. You enter your measurement and your desired levels. The app calculates and adjusts your dosing schedule automatically to compensate for the difference between your desired level and tested level.

The app will also perform a catch-up dose over 48 hours or suspend dosing as needed to adjust levels faster in a safe manner. The app also sets up a reminder to test in a week to continue refining dosing consistently. There’s no better way to approach using a doser to maintain precise levels in an aquarium!

Additional Features Of the System (Primary Control Unit [sold separately] and this Secondary Unit):

  • Create multiple schedules for the same doser and turn them on and off at any time. Handy for testing out different dosing schedules.
  • Set up to schedule doses on a day interval (e.g. every 2 days) or choose specific days of the week (e.g. Mondays and Thursdays)
  • Complete control of dose frequency. You can dose once an hour, once a day or even once every minute. And if you know the total amount you want to dose and the number of times a day you want to dose, the app will do the rest.
  • From the dashboard, view statistics like reservoir levels, upcoming doses, pump speed, calibration volume and scheduled water tests at a glance. Easily access all your settings for that device.
  • Set up and receive alerts and reminders, and review dosing logs to keep you in control of your dosing regimen.

Ridiculously satisfying!
Size: iPad A16 11th/10th, Size: iPad A16 11th/10th
YES! I am completely obsessed with the SPARIN Screen Protector for iPad! From the moment I applied it, my screen looked crystal clear and felt silky smooth like butter under my fingers. The fit is absolutely perfect for both my 11th and 10th generation iPads, hugging every edge without a single bubble or misalignment. I love how responsive it is... swipes, taps, and even intense drawing sessions feel flawless, like my iPad is brand new again. The protector is tough and scratch-resistant, so I can toss it in my bag without worrying about keys or pens ruining my screen. I also love that it doesn’t mess with the display brightness or clarity, so everything still looks vibrant and sharp. Applying it was super easy and stress-free, which honestly surprised me because I expected a million bubbles or frustration. Five stars all the way for a screen protector that makes my iPad feel safe, sleek, and ridiculously satisfying to use every single day!

Happy With The Quality of This Screen Protector
Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13'', Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13''
This is my Amazon review for the SPARIN Screen Protector for iPad Air 13 Inch M4 2026 & M3 2025 & M2 2024 (8th/7th/6th Generation) & iPad Pro 13 Inch M5/M4 (8th/7th Gen), Case Friendly, 2 Pack Tempered Glass, Support Apple Pencil. This is an easy to apply screen saver with few bubbles to smooth out. It is very clear and covers the screen perfectly. I literally can only see it is on because of the cut-out over the camera. It is very thin and transparent. My iPad also responds precisely the same to my touch and pencil, so the touch sensitivity feels great. I am very happy with the quality of this screen protector so far. It seems to be a good quality screen protector. Thanks, Amazon.

Great quality product
Size: iPad A16 11th/10th
This is a great quality product that is easy to apply. It's scratch proof with no glare on the screen. We were able to apply this screen protector with no bubbles on the screen. It's heavy duty and will prevent screen cracking if this is dropped. I would definately recommend this product!

Screen protector
Size: iPad Air 11" M4/ M3/M2, Size: iPad Air 11" M4/ M3/M2
I’m really happy with this screen protector for my iPad. The quality feels really good, and it fits perfectly on the screen without affecting the display quality or touch sensitivity. I was worried it might make the screen look dull or reduce responsiveness with the Apple Pencil, but everything still works super smoothly. It also helps reduce fingerprints and keeps my screen protected from scratches, which gives me peace of mind while carrying it around daily.
