There are easy-to-read markings in milliliters and ounces so you`ll always know how much solution you have available. Tight fitting lids seal without creating a vacuum so they`re easy to remove.

This dosing container is capable of holding all sorts of liquid supplements, top-off water (very handy!), trace elements, even food. Alk, Ca, and Mg are likely choices for reef hobbyists.

If you have a reef aquarium, it is important to keep the water chemistry balanced. Using an automated dosing system is a great way to reduce daily aquarium chores and provide a healthier environment for your wet pets.

Manufacturer Description from Simplicity

This container is perfect for keeping your solutions organized and your sump area neat and clean. Each chamber of the dosing container has markings in both mL and ounces for accurate measurement and tracking of how much of each solution you`re using. Lids are easily removed for quick refills, but sit securely in place when you don`t need to access them—ensuring no foreign materials make their way into your solutions. Each chamber is also equipped with a full length straw.

Nice Container!!

Pros: Large size, uptake tubes to the bottom

Cons: None that I can see

I bought this to replace the off brand dosing container that came with the doser I bought some years ago. I really like the uptake tubes in that they go all the way down to the bottom of the compartment and have an angle to them, thus getting almost ALL the liquid.

Looks Great!

Pros: Looks great and fits inside most stands

Cons: Expensive

Looks great in my Nuvo APS stand next to the 5 gallon ato tank. The only black dosing containers i can find.

Works as described and the lids have gaskets to help seal it.

Great container

Pros: Everything

Cons: Nothing

Awesome. Cheap. Well built. What more can I say. Why spend 200 dollars on a dual container, when you can get a triple container for a fraction of the cost.

Hands down best dosing container on the market!

Pros: Great cost!, Simple yet effective design, sleek look

Cons: Lids are fairly light and don't sit nearly as flush with the rim as I would like them to, can't be stacked with another one

I have a lot of positive things to say on this product and one is it's price point. Its fairly inexpensive taking into account the volume of liquid it holds for each compartment. The measuring marks are easily readable. And the simplistic design and sleek look makes it fit in with any tank set up. I only with it was made to be stacked on another one

The best Container

Pros: Lid without hose attached. Size. Capacity. Price. Price. Price.

Cons: None

You can refill without pulling the tube out. This avoids having to prime the hose again as no air enters the hose when filling. Of course this only works if you fill before it completely runs dry. The float switches are nice to.

Great size for each additive.
