In my opinion, Prodibio is not going to get you colorful corals by itself. It can definitely, in my experience (mileage certainly varies), help clear up your tank, lower nutrients, and maybe as a result of the c-dosing, get better colors by reducing turbidity and allowing more light get to the coral.

However, if you're going for colors / ability to control tweak, I'd look into another product, zeo or FM. That said, prodibio was very effective for me in reducing excessive nutrients. In about 3 months, NO3 and PO4 dropped substantially. It wasn't all prodibio - water changes & good husbandry assisted - it's not magic. Anyway, here's how it went.

# PO4 ~ 0.14
