Ive been using this stuff for years with great results.

I just called the company hotline 866-hth-pool and they claim its 90-95% pure Calcium chloride. The remainder is Sodium chloride, potassium, water, and strontium.

I get it at ACE hardware for $6 for 4.5 lbs. Its made by Arch chemicals.

This may be a good alternate to the dow flake???

Well, I do not care what they say, I want to see an assay sheet on it. 90-95 % , so what is the other 5- 10 % ?

"The remainder is Sodium chloride, potassium, water, and strontium."

[Boomer]

That is not a assay sheet. How much Sodium chloride, how much potassium WHAT???, How much water? How much Strontium WHAT ???? Is one suppose to just assume the Sr++ and K+ are chloride ? 5- 10 % of any of those is allot. 5 -10 % means 10,000 - 50,00 ppm. DOW is 78-80 %(CaCl2 · 2 H2O) the rest is mostly water. Anhydrous calcium chloride (CaCl2) is usually 94 - 97 %. So, that stuff they got is some funny stuff at 90 -95 %. I think it is called plus as it has additives to it, such as extra NaCl, table salt.

I was wondering about using pool calcium also.
The CaCl from bulkreef "looks" (3-4mm pellets) the same as the stuff I put in my pool.
Although, AFAIK, it could all look that way.

[bdare]

Why not just get some of the Tetra CaCl? We all know it's good...

Bulkreef uses Dow flake. You can not go by what it L@@Ks like :)

[SkyPapa]

Yea, Boomer, as I said I didn't know what it is "supposed" to look like.
EDIT, I also didn't know it was Dowflake.
Is it the 'new" stuff or the old.
Ha, that sounds stupid.

It was just a passing thought about the appearancea s I was mixing Bulkreef CaCl.

[Boomer]

Yes, I know, no worry :D

[redspot321]

LOL.... All Im saying is that its cheap, it works, and it comes in convient packages! It looks like they may have changed the formula a bit from the last batch I bought . The SR has been replaced with Mg??

If anyone wants a copy of the MSDS shoot me an email redspot321@gmail.com

One of the concerns with such materials is how much ammonia, copper, cadmium, nickel, etc are in it. There is always some, and possibly too much. that is why to suggest that folks use Dowflake, I tested it and several hobby brands for many of these things:

Hey Randy,

Any chance you'll test Tetra?

[Randy Holmes-Farley]

No, sorry. Too much work. :D

There is no reason to test it. It is made from the Limestone Process and not the Salvay Process, so it is much purer that DOW and has not such thing as ammonia in it. Tetera makes the best calcium chloride there is by assay for us. I spent a hr on the phone with their chief chemist months ago.

An MSDS really tells you nothing about what is in it. It is not an assay. Sceond, this

is allot of bogus as it can't be that pure as it appears with zero % any other ions.

I might add that is allot of Sodium and Potassium in that salt @ 10,000 - 20,000 ppm. If you are using it I hope you are at least doing 30 % water changes / month.

I have 2 words...

SA WEET!

[redspot321]

Where can you get the tetra?

[Boomer]

You will have to contact them to see where you can get it from.

[redspot321]

I emailed a manager at arch chemicals. Heres what he had to say about the Calcium Plus. Hes going to get back to me and let me know who actually makes the stuff....

"This product is not manufactured by Arch Chemicals—we buy the product from our supplier in bulk and package it in bottles"

Could be Tetra...Dow.... the suspense!!!!!!!

[bdare]

I emailed Tetra. They put me in touch with local distributors.

[Dyraxe]

Hello, I have a question for Boomer or anyone else that might know. My question is which type of Calcium Chloride would be best to use from Tetra Chemicals?

http://www.tetrachemicals.com



I was thinking maybe FFC Food Grade or Express RM?

Any info on which is the right one would be greatly appreciated, thank you.

[Randy Holmes-Farley]

IMO, and food grade that lacks the bromide issue that Dow food grades have would be a good choice. :)
