purple up enough for calcium?

Your calcium is a tad low, especially for an SPS tank. The majority of reef keepers like to keep it in the 400-430 range, but almost always above 400. Personally, I don't know everything that is in Purple Up (they don't list it, it's a secret), so I would not trust it to be the only calcium source. I also don't believe Purple Up does anything for coralline growth IMHO. If you want to continue using it though, by all means go ahead, but I would suggest that you supplement mostly with a high quality calcium supplement, and lower the usage of the Purple Up. For smaller tanks, I like to use Kent Liquid Calcium or Kent Turbo Calcium. A two part solution would be an even wiser idea, I like TLF C-Balance.

switching to aragamilk will give you more calcium than purple up with most of the same benifits i believe

On the bottle of Purple up I think it tells you to maintain calcium levels to a particlar number which I do not recall. But as stated above you wanna be over 400, I think going with a calcium supplement is a good idea. I just switeched to Tailored Aquatics Calcium and DKH and so far I am very pleased with the results. I do also add Purple Up on the days I dose calcium and its been working real well for coraline and my SPS.

A Ca of 380ppm is on the low side but wouldn't say unacceptable.

i agree 380 is a bit on the lower side i'm slowly bringing it up to the 400's, mark the reason i started thinking about changing is i'm finding that it's hard to get it too the mid 400's without it falling quickly back down to the 380's, is this because of my alkalinity level? (8 dkH )

It could be because of Alkalinity or Magnesium. Can you tell us your readings for everything that you test for?

calcium is now 380 and magnesium under 1100 last time i checked

OK so what is the supposed benefit of Purple Up? I have been using it since I started my tank 2 months ago, primarily to encourage coraline alagae. I am using Kent salt and my clacium is regularly testing at 500 although my Mg is low.

Is there any benefit to Purple Up at that level of calcium? It tests at that same level with a fresh batch of SW as it prepares for a water change.

Purple up is nothing more than a hugely overpriced calcium supplement, nothing more nothing less. You pay for packaging in a neat little bottle. It is a rip off for what you are getting. That being said it does work, but it costs a lot compared to other supplements/ways of doing things. It doesn't build coraline algae at all, good water parameters, a source or coraline to begin with build coralline algae. Even strong metal halides deter coralline...it lt thrives in a bit darker...Most of my tanks that had super corraline growth, i mean inches think were all on the undersides of rock, and all grew in the tanks that had the most vho actinics. It's present everywhere but thrices in the darker areas..and yes all colors. the more shade the darker/more intese the color (whatever it was). Compare calcium supplements, and buy the cheapest/least hassle free way for YOU do dose your aquarium. Regardless of what anyone else says. If it's convienent for you but not the way others do it, who cares. But you are paying way to much for what it does...way way to much.

are you really finding that little use out of it as a coraline enhancer? i've found that my tank's getting much faster corraline growth than per say people who are using 2-part/1-part like liquid reactor, like mik_101's tank, much slower coralline growth. then again you might have a point, i am maintaining my alkalinity and calcium in order. interesting how you found that you're dimmer tanks are getting quickewr corraline growth, the tops of all my rock are covered and bottoms where it's dark are bare
