Calcium carbonate and phosphates

[xmjxflipx]

@Randy Holmes-Farley wanted to inquire can dosing calcium.carbonaye powder reduce phosphates based on grams?

Zeovit has coral snow plus which seems like a increased dosage of calcium carbonate that removes 8 mg of phosphate supposedly per 1 ml per 25 gallons. Do you think this mixture is a mix of calcium carbonate with some lanthanum chloride diluted?

Calcium carbonate will bind phosphate. The smaller the particle size, the more effective it will be per gram due to the higher surface area.

Have any idea like 1 tsp per 25 gallon can bind hie much of phosphate in general

Just thinking about the numbers, 8 mg of phosphate in 25 gallons or about 100 liters is roughly a reduction of 0.08 ppm. One gram to do this type of reduction might be an overly optimistic vendor claim.

Zeovit has coral snow plus

I’m pretty positive coral snow plus is calcium carbonate + lanthanum chloride.

What’s the evidence? Is the claim even true? I am in the dark on this product.

I apologize. I can’t remember where I read it, but a few users and I suspect it is lanthanum chloride.

The regular coral snow is assumed to be just calcium carbonate.

This is the manufacturer claim about this product:

“Coral Snow is the well-tried problem solver from Korallenzucht.de. The Plus Version Coral Snow Plus reduces your phosphates in reef tanks in a simple and easy way and helps to keep it at low level without up- and downturns.”

I’ve read some users dosing it and seeing a nice phosphate drop.

I highly suspect it contains lanthanum chloride, but I do not have evidence. I apologize for misspeaking.

Yeah zeovit normally keeps there ingredients proprietary I think. If you used lanthanum chloride and it's in icp tests....is the build up of lanthanum very bad for a reef tank?

I don't believe that used correctly with appropriate filtration to remove the precipitant and the calcium carbonate suspension there would be any easily measurable lanthanum accumulation in the tank.

Thanks.

I wonder if I tested it in the lab it would reduce a phosphate concentration? It wouldn’t address the content question unless I washed the coral snow first and demonstrated a difference in phosphate reduction.

You could fine filter it and test the clear filtrate for phosphate removal,

So close to being side tracked again :)

Now not so close to being side track. The magic elixir costs $60 for 250 mL!

Of course it does. lol
