The planted tank subject can be somewhat daunting for the newcomer and less 'scientific'. Here's a useful list of commonly used chemical names, acryonms and abbreviations etc.

Courtest of Tom Barr's - The Barr Report.

Those chemical names and acroynms! Add more if you see one I missed!!!

Useful, although it would be nice if there was one definitive list rather than lots of lists with mostly the same stuff.

BTW, I didn't see CEC in there....
 
hey these information tend to be more usefula nd informative. i think this can for sure enhance our knwoledge. thanks for sharing ....
 
Yeah very handy George, thanks for the link. I have on many occasions had to use Google to go find information on Chemical names etc and this list will save me a lot of time :)

Cheers,
 
There are a few more that are frequently used on here, which would be useful to get added. Took me a few posts to work out what everyone was talking about!

FTS - Full Tank Shot
FE - Fire Extinguisher
DSM - Dry Start Method
TNC - The Nutrient Company ( ;) see here!)

Plus others frequently seen that may not be understood by complete newbies..

HC - Hemianthus callitrichoides
HM - Hemianthus micranthemoides

Thank you for sharing the link, I'm a new memeber and learning about this all ahead of getting my own tank so this is very useful, thanks! 👍
