to promote growth of Coralline algae, you can add
a product called PURPLE-UP. It does work; just not
over night, it takes some time.

How can you say it does work ?
I have never used it, but I have plenty of coraline...
Have you done two tanks test, one with, the other
without the product to compare how fast will it grow?

I would not promote product like this if I was not
sure if it really works... coraline grows fine in
every tank without any addition of "purple-up".
Just keep the calcium level high and water clean and
you will get it, without spending money on snake oil.

I would not call purple up "snake oil", but using the two
parts would be better. Purple up is just calcium and
alkalinity additive. Using a two part gives better
controle of calcium and alkalinity.

It would be honest if they call it just calcium additive.
Instead they claim their product does what happens
naturally in the healthy reef tank.
