I actually quit measuring it. I just put some in and say 'yeah, that looks good'. It's cheap enough to the point that the dose doesn't really matter
KZ Coral Snow = Chalk?

Lol, ok ok. I guess I was expecting more from something KZ that would cost so much. I guess that's enough, how effective is it?

Take a look at the pics above. It's pretty insane what something so simple can do to what we think is already really clear water.
I Think this stuff is why KZ gets away with running a small baggie of carbon passively rather then a reactor full! My tank is at work and I dose first thing when I get there at 7:30. By the time the lights come on an hour later its clear. For the cost of the stuff on amazon there is no reason I see not to at least try it.

Any advantage to getting 99.9% pure over 97% ?

Unless it's cheaper, probably not.

I think it will really help my son's aquarium. He and my wife tend to over feed, it has a skimmer that works ok but hopefully this will help much more.

I agree that both of those likely are fine.

I bought 10lbs bag of the 97%. According to Amazon I started using it soon after April 4th 2016.

Here's what I use and mix up. Then just shake and add a tablespoon to my 180.
Add 18tbs CaCO3 then add RODI to the 900ml line.

If you know a litle chemistry than you know that CaCO3 is not soluble in water.Its just snake oil.All our sand and live rock or dead corals skeletons are made of calcium carbonate but that doesnt disolve in water.To disolve the CACO3 you need to add CO2 thats why you see people using calcium reactors where they melt lime stone or dead coral skeleton by using CO2.Kalkwasser on the otther hand is much better than CACO3 because that makes calcium available.Calcium is good ,,floculant,,because calcium bonds the fosfates bestter than GFO in salt water or fresh water but with a ph above 7 ,resulting calcium fosfate(the substance from what human bones are made of).

I'm not sure I understand the conclusion of your post between the opening and the ending.
I don't think anyone has proposed that this is a method to supplement Ca. Only that it may be useful as a flocculant to help skimming or other types of mechanical filtration.

To get a conclusion you have to read the quote to wich i was giving the reply.That user sayd CACO3 is better than kalk(CAOH) wich is totally wrong.Caco3 is just tossed limestone and it isnt soluble in water just like sand is-it will deposit on the bottom.It wont ,,floculate,, nothing.The real stuff that makes water clear as in thoose pictures is kalk because the calcium in calk is available in the water solution and that calcium bonds to the phosphates that make the floating detritus.A lot of people use kalkwasser mainly to keep theyr water clear and not necesarely for adding calcium or keep the alk stable(like the soft corals aquarium that use kalkwater in the top off).I assumed that the KZ product was kalk (never measured to see the ph of the coral snow)but if its just tossed up limestone(caco3) its even worse than if it was kalk
.This is just my opinion on the matter but nobody keeps you from pouring tossed limmestone into the aquarium.It wouldnt hurt nothing for sure.

Read the post you quoted would be a good idea. No mention of better or worse was made and stated what you are arguing that CaCO3 is not limewater. Maybe you quoted the wrong post?
There's some evidence that dosing lime may bind phosphates but not a significant amount. At least it has not been shown in practice afaik.
Under: "What Else Does Limewater Do In An Aquarium? Reduce Phosphate"

There are some reasons to believe CaCO3 could help remove some metals and that PO4 could bind to it as well then get filtered out.

You're thinking that calcium carbonate is being added in an attempt to raise cal and alk levels, which is not the case.Calcium carbonate (CaCO3) will not dissolve in a reef aquarium under normal circumstances. What it does, however, is act as a flocculent, binding small particulates along with some yellow dissolved organic matter (aka gelbstoff) to its surface, which will then be much more easily removed by the protein skimmer in the system (or really fine mechanical filtration). Some phosphate could also bind, but mostly at the higher end of a reef aquarium pH scale, and with my tank running a pH of 7.7-7.8, I have never personally measured any change in that regard. A far better binder for phosphate is lanthanum chloride.
Kalkwasser (CaOH) when added to a reef aquarium will react with CO2 in the water and will separate into calcium and carbonate/bicarbonate. This will raise calcium and alkalinity levels, raise pH significantly if not dosed in small quantities, and can precipitate some phosphate which will bind with some organics for easier removal via skimming. Kalk generally should have little on water discoloration or turbidity as only minor amounts of organics will be bound.
The binding effect of CaCO3 can be significant - see the photos in post 36 by Reefer PT. I can confirm those results. My well water after going through a $3000 purification system isn't even as clear as the 'after' results.
I love when you talk about a kz product like coral snow, people make "snake oil" statements. I have not done any scientific studies, but the results seem pretty outstanding to me. As for it precipitating out. I run a bare bottom tank and have noticed no more "sand" on the bottom then what I saw before dosing.
