Is Caribsea Purple Up safe to use with skimmers or will it throw it out of whack?

It contains fine calcium carbonate (aka sand). It is NOT soluble in seawater. From a chemistry standpoint I can't see how it could possibly do anything other than settle on the bottom of your tank.

To me it is a waste of money and really won't do anything to add coralline growth to your tank. It's best to get a snail that has some on it or even a piece of LR from your LFS to "seed" the coralline. Then keep all of your parameters in check and it will grow. I also suggest if you don't want it to grow on the sides and back glass that you start scrapping it off as soon as it starts to keep the glass clean. It's no fun to clean it off once it takes hold, even on glass.

Is there some reason to not let it grow on the back glass? I have always liked the purple color on the back glass? Eventually it will cover most of it.

Like way too many additives in this hobby, it's 'snake oil' and a waste of money. They gave a bunch of it to our local club to raffle off and nobody wants it!

No reason what so ever. Some folks do not like it anywhere on the glass. I personally keep the sides and front clear but the back is covered. it is personal preference. good luck

Like a few above have said it's an expensive sand with a bit of magnesium and a couple other trace elements.
There is a case that it could be used as a flocculent allowing more light to penetrate through the water or that the fine sand may give a slightly better surface for the coraline algae to grow on.
But there's much better choices for that like a much cheaper version of KZ coral snow by dosing Calcium Carbonate
