There are lots of reasons why Purple Up may have worked for you, and it may even be the product itself (or coincidence, etc). Cheers!

Btw, it is often the case that low alkalinity is a limiting factor in coralline growth. Purple Up would provide that for you to a certain extent. Are you testing calcium, alkalinity, and magnesium?

Someone's a touch sensitive.

Ditto, don't take offense. This hobby engenders strong opinions.

In my experience basic good calcium/alkalinity will promote coraline algae. If if makes sense for you to add it through Purple Up, do as you see fit. I read awhile back that strontium may be a limiting factor in coraline growth and perhaps "Purple Up" supplements this as well. When I first started out (8+ years ago) I was worried I wasn't getting enough coraline growth and I was adding a strontium supplement. A few years later (well after I stopped adding strontium, but after installing a calcium reactor) It was hard to keep with the required scrapping of coraline on the viewing panes.

Happy Reefing.
