David Ekers
Perfect for my 40G / 150l reef

> Smaller form factor - perfect for smaller systems.
(Looks SUPER with my GHL stack)
> Compartments do not share a wall - will not leak from one compartment to the next.
> Lids fit with close tolerances - quality build prevents excessive exposure to room air/dust.
> Hmmm....I would need make something up to complain about.
> Three short silicone tubes were included with my dose 3L. - about 4 inches/ 100mm. I'm using then to adapt the pick up tubes to my dosing tubes. Stretches over the tubes to form a tight seal.

I may get three GHL magnetic stirrers for this to rest on. It would be really nice to be able to make sure everything stays in suspension.

No regrets, this is a great product!

Great, little Dosing Containers

Emphasis on little! I can't understand why nobody makes a dosing container under 1 1/2 - 2L? We don't all have 400 gallon systems!!

This setup is very well built and compact. If you buy 2-part and other additives in 16 oz bottles, then this container is a perfect fit.
Love it!
