Talk:Carbonate hardness

[Untitled]

I suggest that both Carbonate alkalinity and Carbonate hardness be merged with Hard water. Biscuittin (talk) 22:03, 31 October 2010 (UTC)

Why? Carbonate hardness can be present in soft water too, it is also of interest to fish keepers as it is relevant to pH. Kat (talk) 08:08, 3 September 2011 (UTC)

• Oppose - The two are related, but significantly different concepts. Kat (talk) 08:29, 3 September 2011 (UTC)
• Oppose - The two concepts are not even related, except as a source of confusion due to the common mistake of using the term: Carbonate "hardness" to refer to a certain type of alkalinity. Alkalinity of any kind or degree does not in itself cause water to become "hard", although the two things often occur together in natural waters due to certain dissolved minerals (CaCO₃, MgCO₃) causing an increase in both alkalinity and hardness simultaneously. However -- carbonate hardness and carbonate alkalinity refer to exactly the same concept, and should be merged together into a single article of their own, with the primary title being "Carbonate Alkalinity", and "Carbonate Hardness" being a re-direct to it. It appears that the carbonate hardness article was initially written by aquarists, whereas the carbonate alkalinity article was written by chemists. Both have useful information which should be preserved in a merged article. I will make this change in the proposed merge.--Turjan (talk) 15:08, 4 November 2011 (UTC)

Looking at this some more, I now think that the best solution would be for carbonate hardness to be a disambiguation page that links to carbonate alkalinity and temporary hardness, since it seems that it is sometimes used in the latter sense as well. Most of the content here should then be moved into carbonate alkalinity.--Turjan (talk) 17:07, 4 November 2011 (UTC)

I agree with adding a disambiguation link to this page.Millertime246 (talk) 14:06, 6 February 2012 (UTC)
