Rocks/gravel at pond bottom

They didn’t publish the brochure. Don't quote me, but I think it was published by the DNR or something similar. I will have to look. They didn't have anything but plants for the pond either, so I doubt they were trying to get me to buy "miracle" solutions. The brochure also was against putting any type of chemical in your ponds. It was about letting MOTHER NATURE do its stuff.

Before you get all high and mighty, you might want to know what the hell you are talking about. ;)
I do know what I am talking about.

This is a fish forum and you mentioned the brochure... so that brochure isn't even applicable to ponds with fish. I guess with plants only, there won't be any fish waste so the substrate won't matter as much. Maybe you shouldn't reference publications that have nothing to do with the question if you don't want the publication contradicted.

And just because the Dept. Of Natural Resources publishes something, that doesn't make it right. Government usually gets more things wrong than right at a very high price to us tax payers... IMO. Just ask my neighbors about the levees designed and built by the Corp Of Engineers down here in the New Orleans area.

I don't know why you got all offended since I was picking on the brochure, not you. There is simply no way a "brochure" with 20 questions/myths can give people adequate information so the DNR wasted the taxpayers money publishing it in the first place.
 
I would point you to a very long thread we recently had in the Ponds-Koi Yahoo Group about rocks/gravel substrate in a Koi pond and then you will really see how bad that brochure information is... at least when it comes to rocks in a Koi pond.
 
I clean my pond out thoroughly twice a year (once in early spring, and once in late fall). I also have plants planted directly into the gravel; they use the fish mulm as fertilizer. And of course I don't overstock my pond with too many fish!
