Mag fluoride

I have magnesium in a bottle.
I got it a year ago in Oakland because I was experimenting balances between Ca+ and Mag. to try to increase KH and Ca+. at the end with time everything balanced out by itself (especially once i changed salt mix).

Tonight I'll check if what I have at home is magnesium Fluoride or something else.
 
let me check at home i have one of them....my comp is not hooked up at home so i'll have to let ypou know tue, i can bring it to the meeting. Let me know if you need it beofre that.
 
Tom, what's the difference between the magnesium fluoride compound and magnesium sulfate? (besides fluorine and sulfur! :))

Thanks.
 
fluoride is a much more inert element than sulfate or chloride, both of which play important parts in the ionic balance of the water (and sulfate is not a good thing to add -- its toxicity is of concern and its bio-activity makes it an undesirable ingredient in an additive
most of us dont worry much about this, and we use magnesium chloride. but i guess tom is being very careful not to upset the ion balance in his system.

Adam, I'm going to have to take issue with your statement, mostly because I know you know better. :D Fluoride is a compound based on the association of the element flourine with other elements and compounds.

Here are some other statements about fluorides and fluorine I found:

Fluoride-containing compounds are so diverse that it is not possible to generalize on their toxicity, which depends on their reactivity and structure...

A few organofluorine compounds are extremely toxic, such as organophosphates like sarin and diisopropylfluorophosphate that react with the cholinesterase enzyme at neuromuscular junctions and thus block the transmission of nerve impulses to the muscles.

Everyone remember sarin gas from the Tokyo subway attacks in 1995?

Interestingly, magnesium chloride has a number of uses:

Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk.

Magnesium chloride is used for a variety of other applications besides the production of magnesium: the manufacture of textiles, paper, fireproofing agents, cements and refrigeration brine,[5] and dust and erosion control.

Here's a statement about magnesium sulfate I found:

Magnesium sulfate heptahydrate is also used to maintain the magnesium concentration in marine aquaria which contain large amounts of stony corals as it is slowly depleted in their calcification process. In a magnesium-deficient marine aquarium calcium and alkalinity concentrations are very difficult to control because not enough magnesium is present to stabilize these ions in the saltwater and prevent their spontaneous precipitation into calcium carbonate.

I would be interested in learning about the comparative effects of chloride and sulfate disassociated from magnesium in reef aquaria. Anybody know?
 
Very true ken, some fluoride compounds are super toxic an I didn't even think of them like flouride containing pesticides. But in terms of he compounds we were discussing, magnesium fluoride is the most inert bioactive source of mag -- magnesium sulfide and magnesium chloride are much more likely to have an impact on ion balance than thei fluoride counterpart.
 
Organofluorides!
And there are even fluoride based antibiotics (I've been on em once -- NOT fun stuff!) called fluoroquinolones that are all kinds of scary...
 
Dang you guys are like mad chemist...i took organic chem in college...lets just say i switched my degree after that class. I got my only "D" in my academic career. Hated the class...but i did learn some cool stuff. Do you know how calories are figured out?..... it is burned. We put a nut on a needle and lit it on fire under a small amount of water; the change in temp is put in a conversation that gives you calories. I'm sure there are other ways but this was one of my favs in college.
 
yeah! ive done that one!!
1 cal is the energy it takes to raise one gram of water by 1*C
but in nutrition we use the term calories to refer to kilacalories, the amt of energy needed to raise one kg of water by 1*c...
 
Any body has any extra Magnesium Fluoride?

What made you decide to use Fluoride Tom? I don't believe I have ever heard of it. I don't worry about Magnesium levels that much but if I do want to boost the level I use Seachem Reef Advantage. This is a mixture of calciulm chloride and sulfate supposedly in the proper ratio of NSW levels as to not create an imbalance.
 
Steve, it's interesting that you haven't had any issues necessitating magnesium intervention. I had some sps rtn issues many months ago and when I investigated my water chemistry I discovered my magnesium was very low (<900). I automated my dosing including the addition of mag ever since and haven't had any rtn issues. At the moment I'm keeping my mag level up at 1500 to help combat bryopsis and it's working. :) Once it's gone I'll drop the mag level back down to 1300ish.
 
Interesting article Tom. However, it does not evaluate the use of magnesium fluoride, only magnesium chloride and magnesium sulfate. Also, the use of most brands of magnesium chloride is not recommended due to contamination with bad things such as ammonia. The article leans towards recommending a mix of magnesium sulfate and magnesium chloride as a more optimal long term supplement. It would be great if Randy could compare / address magnesium fluoride as well.
