Unless I am wrong isn't it Calcium hydroxide? there is no carbonate portion to it or contained within it.Shaun,
I'm not advocating one over the other here ,I'm a 2 part guy myself, but I was always under the impression that kalkwasser is a balanced additive too. Isn't this what made it possible for the early Gerrman Reefers to suceed? Randy
Make it yourself. It is really easy to follow Randy Holmes-Farley's recipe. Cheap too!solbby, You just totally said what I have been leading up too for a long time. from what I have been hearing and what I have learned on my own has been the same that ca and co reactors will not do what the the 2 part supplement can do and much better. my only problem is that with a system that is 1000 gallons, what would be more economical? I would love to not have to deal with 2 reactors and two more things that can fail. most of the experts have been saying to just keep it simple. dosing is better than all the reactors in the world and more acurate and foolproof.
looks like in the meantime i just may go without any reactors and just dose. just have to find the cheapest way of finding the 2 part.

Yes you did! :shhh: :lol2: See that is what I get for taking Chemistry :banghead: , makes me remember my loathing of Physical chemistry.Did I just catch you on a hard science question????? I can go to my grave happy now. LOL
I reponse to your questions, you have now moved beyond my ability to respond. Bingman's work is very good on the subject, and I believe Holmes-Farley too has written a fair ammount on the subject.
Cheers,

I use Kalkwasser as a ph stabilizer, with a side benefit of calcium and you still have to dose calcium chloride with sodium bicarbonate (pH value of 7.0) and sodium carbonate (to bring up the pH value of the sodium bicarbonate).

I wonder what the writer means by "it quickly combines with atmospheric and in-tank CO2 and bicarbonate to form bicarbonate and carbonate".
The "atmospheric" CO2 is probably the surface of the water. You're getting (a bit) of reacton at the water's surface. That's why kalk reactors are usually sealed containers.

Meaning wouldn't it combine with CO2 in-tank only. Additionally to think that the hydroxide ion will only form with CO2 is a mistake, I would think that it would react with a number of different molecules. If not enough CO2 is present then carbonate could be limiting.
