I fail to see any logic in this pair of statements. What you are saying is:
"If you have mud, you have the correct nutrients, QED." As someone pointed
out, all mud is not created equal.
And, of course, you are implying that "If you don't have mud, your plants
will not grow was well as they would if they had mud."
I don't have mud in my tanks and I would opine that my plants grow better
than your plants. Dueling photos at High Noon?

Yes, mud may have more nutrients than sand, sand+laterite or sand+laterite+
proper fertilizers. In fact, mud has TOO MANY nutrients and will, in fact,
lead to algae problems. When you use mud, you DO NOT have control over the
nutrient level in your tank. If you use mud for a substrate, you are
quaranteed to have an algae problem. Review some of your own postings if
you don't beleive me.

I think it's more a buzz word used by newbies. As far as I know, only two
products claim to use laterite: Duplarit and Substrate Gold. All the other
buzz about laterite comes from people using art clay, red Georgia (not
relation) clay and any other red dirt that turns up and calling it

Wow, was there *almost* a recommendation there? So close, yet so far.
