In an effort to stand behind a product we support, use, and distribute, we have been running a test for awhile.
We have multiple coral systems running with different dosing regimes depending on the corals they house.
On one of our last Fiji orders we set aside two Bink Birdsnests in two seperate systems. Amoungst other dosing regimes, in one system we use the Fauna Marin Ultra Organic and in one system we do not dose it.
Can you see the difference?
