Brightwell Aquatics Kalk+2 - Advanced Kalkwasser Supplement w/Calc., Stron., Mag.

[Charlie's Angel]

Does anyone us this or is anyone familiar with it?

Still researching things?

[bertoni]

I've never heard of it. Can you provide a link? I don't see how a kalk-based supplement can provide magnesium, off-hand.

I'd like to check it out too. Magnesium in limewater is a poor idea, since it won't dissolve.

everything on their site is flash so it is hard to link to

they have msds sheets in pdf form

Beat me too it...thanks for providing the link...I found it on Champions Lighting ... I know nothing about chemistry but this would be nice if it worked.

Hydroxides of calcium, magnesium and strontium. I don't see how the magnesium would work all that well. I suppose if the solution was stirred and the magnesium pumped into the tank as a precipitate, it might then dissolve. Sounds messy, though.

[Randy Holmes-Farley]

So sad. Another case of a company not understanding their own product. At least I hope that's the case, and it is not an intentional scam.

"Formulated by a marine scientist"

Well, that marine scientist apparently does not understand chemistry, and apparently did not read my article where I demonstrated that such a product could not work the way he describes.

No, it cannot be used like normal limewater, as the magnesium will be totally insoluble and will settle to the bottom of a reactor or a still limewater reservoir. But he also says it should not be dosed directly, and must be dissolved first, so there is no way to use the magnesium.

I show that magnesium settles out of limewater here:

Thanks guys

Happy Reefing.

The person who owns that site is Kent, Formerly the scientist for All/most of the Kent Products.
So i am sure he knows his science.. What makes me worried is that is his new stuff isn't good, then how OFF is the Kent Supplies...=O

[Randy Holmes-Farley]

Yes. Unfortunately, he took some bad ideas that Kent used for products with him. I've debated Kent liquid reactor with him, since I believe cannot function as Kent claims. He did little to convince me he knew what he was talking about, aside from the party line defense of the product concept.

He now has a product, Liquid Reef, that sounds to me like Liquid Reactor (or Purple Up) made worse by adding calcium, making it an unbalanced additive. Not sure what situation someone would want to use that, even if it worked as claimed.
