Advice on two products

I'm looking for advice/opinions on two different products:

The first is Chemi-Pure. First just let me explain that I don't believe the claims that you never have to do water changes if you use it.

I use several units in a canister filter and wanted to get some opinions on if there is something better to use along with regular maintence.

I also was wondering about a CaribSea product called PurpleUP. Anyone have ant experience with this colarine alge booster?

Never used Purple Up, but I haven't heard terribly good things about it.

Chemi-Pure I have used, and it seems to be a mix of carbon and a syntethic resin. Does a good job, but similar results can probably be had by using plain old carbon. I switched to Black Diamond myself out of cost issues.
125G Reef with 40G sump/fuge.
2x 250w 14k MH, H&S A150-F2001 Skimmer, 3x Tunze 6045, MW No3 Reactor, Coralife Ca Reactor. Mostly softies with a metric tonne of Zoanthids.

Most carbon is just carbon. Change it once a month or more often. Purple up can not match steady parameters. So just keep your parameters straight and you will be fine. Let it come on its own. You can get spores from another tank, by scrapping the walls of that tank and putting the scrappings into your tank.
I skim wet, therefore I am.

Instead of Chemi Pure, I'd use a good quality activated carbon. I don't believe that the ion exchange resins in Chemi pure do much that is useful in seawater.

The main ingredient in Purple Up, fine aragonite, is essentially fine sand and will not dissolve in the aquarium, despite faulty claims by the various sellers of such products. So IMO, Purple Up is just a trace element cocktail of unknown utility since it doesn't really say what it contains. I'd avoid it.

I review calcium carbonate supplements (like Aragamight, etc.) in this article:
