Purple up

Do any of you use purple up? What do you think of it?

from reading the ingredients it is just calcium and some trace elements

I believe is just nutrients to help the good algae grow.

If your keeping LPS or SPS I think your already providing the right conditions for coralline algae

The calcium and alkalinity that are supposedly in it in the form of fine aragonite are not useful for that purpose. The aragonite will not dissolve in seawater. It is just an expensive type of fine sand that can mislead testing if still suspended in the water as it will dissolve in an alk test and maybe in a calcium test too.

The other ingredients may or may not be useful for you, just like any other cocktail of elements that is intended for dosing to a tank that may need some and already have too many of others.

Salt mixes probably have most, if not all, nutrients needed.

I use it. I bought the 16 oz bottle a long time ago and I still have some left. Every time I clean my tank I add it, like once every week or once every two weeks. I didn't have that much coralline algae so I bought a small live rock covered in purple coralline algae and and used purple up and in like a month you will see the difference.

Stuff is no good. I dosed at half strength trying to grow coralline fast. End up with calcium at 800 and lots of dead corals. Bad stuff, bad. Very bad.
