New RANDY's 2 part

Hi randy sorry if im late on the topic. I've been using a Ca reactor these past few months and it has not been working out lately.

I'm looking forward to going back to randy's two part. But here's the problem. recently dow changed their chemical composition of their Dow Flake to contain elevated levels of boron. Thus dowflake is ruled out.

There are other types of CaCl that im wondering if we can use this and to what proportions to gallon jugs.

Types of CaCl:
-peladow
-Briner's choice - calcium chloride

Has there been any change to the peladow? Also when using peladow is it just 20% less than the DowFlake Proportion with Randy's Ca #1?

I was an active user of DowFlake a few years ago and I was wondering what you thought about the peladow formula.

What other product would you consider using with less impurities and their proportions to a gallon of water?

Randy your help would be greatly appreciated.

Thank you so much,
AL

Peladow is made the same way as the flake, I believe. TwoPartSolutions.com is selling calcium chloride that they claim is okay, and I haven't heard any problems with it reported. The Tetra food-grade products seem to be fine, so the Briner's Choice might be okay. Is that by Tetra?

hmm curious though if theres one more pure CaCL to use rather than the rest. I have no idea as to what proportion to use the CaCl that twopartsolutions.com sells. I just found something on Tetra no idea who they are unless the yare that goldfish food company lol. Briner's choice is another Dow chemical product supposidly its cleaner.

If peladow is made the same way as flake has their recipe increased in boron as well???

thanks for responding jonathan greatly appreciated.

Yes, I think PelaDow is the same in bromine. I think it's actually bromine that is the issue.

Tetra is a very large producer of CaCl2:

According to this Dow information, bromide is rising substantially in every Dow calcium chloride product. None are suitable for continual use in a reef aquarium.

http://www.dow.com/calcium/news/August_2005.pdf

You'd need to find a different product line.

FWIW, I do not know what other brands might be suitable, and what might not.

I think I'll have to put a disclaimer in the the online article.

Actually, limewater may be a better option as it is still cheap.

i feel bad for twopartsolution.com unless they come come up with an alternative because eventually they will run out of the good stuff. They have great prices on other things as well though.......

I do not know that food grade is necessarily acceptable. The bromide in Dow's food grade rose along with all its other types of calcium chloride. It is the same level as in the new Dowflake.

No, sorry. I'm happy to look at specs, but I don't have time to do experiments.

thats understandable.if some of us come up with specs that you can look at, approve or disapprove,that is a start in the right direction.i personally do not dose with 2 part solution,i am old school kalk and calcium reactors,but alot of new hobbiests in my reef club use two part.

so is the two part no good now, even if I order a batch from 2partsolutions today? i'm very new and unfamiliar when it comes to dosing two part, and was just doing some more reading on it before i ordered. it all sounded so cheap and great. any available alternatives that would be as cheap?

Anybody know if the same is true regarding Prestone Driveway Heat? I'm curious if it is also a Dow product?

And Randy (or someone else), do we know what chemical form of bromine is in the new Dow? I was under the impression that many Halogens were able to evaporate out of solution if let stand long enough. Been a long time since I took Chemistry though
