i was amazed the first time i saw a planted tank.
when i asked the owner how i could do that, i was overwhelmed with the vocabulary, and quickly checked out of the conversation. but i did manage to retain the name, "tom barr," and my personal search began.
the title of this topic is not my own. it's a reiteration of mr barr's thread title.

i do commend this to those who are curious, but discouraged trying to reconcile the scads of positive/negative anecdotes on the subject.
it's not like reading a primer on spelling. but tom uses a consistant vocabulary which made it easy for me to learn.
i found it helpful, and it lead to reading several other posts of his. i hope you find it helpful too.
