Objection to use of generic term 'algae' in the article.[edit]

Most articles about water quality of lakes mention algae and algal blooms, these words in fact specifically refer to Blue Green algae and Green algae only and not to Diatom algae.

Diatom algae blooms do not generally occur in nature in inland water-bodies, they do occur in estuaries and oceans.

I would like to object to the generalised use of the word algae since we are offering a solution to Eutrophication of lakes by causing a Diatom algae bloom to control Blue Green algae blooms. While this may prima facie appear to be difficult to believe, we can confirm that for the past 4 years we have used our product in a few lakes in Bangalore, India to achieve this objective.

We can convert Eutrophic lakes into Oligotrophic lakes by promoting the growth of Diatom Algae. Its conventionally believed that Diatoms are difficult to grow but when our product this is very easy.

That sounds interesting. Have you published anything on it? If so, I'd be interested in reading it---to satisfy my own curiosity. With regards to the article, I'm not sure this is the place to get into the distinctions. Perhaps that would be more appropriate on the Algae page.

I agree. Lets leave that to the algae page. Chogg (talk) 09:30, 1 March 2011 (UTC)

Correct portal[edit]

Can we add this to the ecology or geography portal? It isn't really chemistry.

Also, is it really true that deep lakes often have high oxygen content? I would have thought that deep lakes are not well mixed in their depths and thus suffer low oxygen. This is certainly the case in Lake Iseo and I either lake Milawi or Tanganyika. Chogg (talk) 09:30, 1 March 2011 (UTC)

Do deep lakes have high oxygen content? I was also under the impression that deeper waters tend to be more anoxic. The article doesn't say that, does it?

Incidentally, I just now noticed what you meant re. the chemistry portal. I agree, and am changing it to ecology. After reviewing the ecology and environment projects, I went with both...

Mergers[edit]

Four article stubs were floating out there (get the pun?) all alone, and they fit this page well, so I put them here.

Oligotrophic[edit]

Mesotrophic[edit]

Eutrophic[edit]

Hypereutrophic[edit]
