New RANDY's 2 part

[doovid]

Thanks Randy! The calcium chloride is considered food grade; here's the website:http://www.cal-chlor.com.

Also, when you say you developed exact measurements are you saying only when using the baked baking soda, or is there a conversion when using calcium chloride (I'm not sure if store bought baking soda differs from the chemical compound)?? I'm wanting to experiment with the 2-part method and am also interested in attempting to put together websites where everyone can get the best prices for quality chemicals.

OOpps...I'm getting things mixed up!! I'm meaning sodium bicarbonate as a direct replacement for the baking soda. Another dumb question, can sodium carbonate (soda ash) be used instead of baking soda?
One website that sells both bulk sodium bicarbonate and calcium chloride is :http://www.cal-chlor.com/tech_products.htm. Another is: www.cqconcepts.com.

Recipe 1 is made with baked baking soda which is equivalent to sodium carbonate, just note that because the recipe measures the baking soda before baking it to turn it into sodium carbonate you may need to adjust the measured ammount.
Note also that the purity of sodium carbonate (Washing Sada) sold for laundry at the supermarket is in doubt and at this time not recommended to be used.

Sodium bicarbonate of the required purity will be a direct replacement for the baking soda which is pure sodium bicarbonate.

Unfortunately, food grade calcium chloride does not ensure that the bromide level isn't excessive, as it now is in Dow's food grade calcium chloride.

But that said, the elevated bromide might not actually cause folks apparent problems.

i will be ordering the tetra brand calcium chloride food grade. i have contacted the manufacturer and they state that there is no bromide in their product. hopefully this product works out.

 

[Randy Holmes-Farley]

Sounds good.

FWIW, I've begun to think the Dowflake may not be so bad after all:

A simple question from a 2 part newbee...be kind Randy, lol...

I am setting up a 22 gal reef and will be dosing 2 part via a pair of Drew's pumps. I am concerned about dosing all the mag at once in such a small tank. Should I setup a separate dosing pump for the mag or could I add the mag to my 2.5 gal ATO tank and dose as I top off?

I really wouldn't even worry about mag. I dose it just every now and then. When you do water changes just get the mag up to the level you want and dose it that way.

Hi Randy, I am about to purchase some calcium chloride and Mag chloride from BRS and and have a question for you. I use IO salt and I remember you saying somewhere that when you do water changes you don't measure CA and MG but rely on IO having the same levels as always and just dose a required amount. What would the required amount of Calcium Chloride and Mag Chloride be for a 25 gal water change using instant ocean? Thanks in advance.

Regards,
Craig

I boost my IO by 70 ppm calcium and 150 ppm magnesium. Use this calculator:

Thanks Randy.

:thumbsup:

Happy reefing.

Randy I've looked and could not find out if you think this stuff is safe or not. Any advice?
I've seen people say it was the same thing as the prestone but I'd like more of an expert opinion. I have new bags of this is why I'm concerned or if just buy something else. I appreciate the help.

It might be fine, but there's no way to be sure without a lot of expensive testing. People have been successful with a wide range of calcium chloride products, though.
