Re: sulfate and H2S production, and thanks.


I am very interested in the issue of sulfate content of water, and its 
relationship to H2S formation in the substrate.  If anyone has data on 
this effect, anecdotal or otherwise, I would love to hear about it.

While I'm at it, it would be interesting to hear data about Cl-, and any 
biological effects of excessive chloride ion content on the inhabitants 
of freshwater tanks.

Also, I thank all the individuals who responded to my list of questions 
about the chemistry of freshwater planted tanks.
