water gardener / gold fish and shubunkins
True. but over the surface of my bog I have zero areas that have a strong flow of water, ie channeling. It perks up over the entire surface.Not sure having the water run clean on a backflow proves it isn't caking.
I did, one time, dig down to the bottom, x years ago, in a few spots. Everybody was saying the gravel water would stink unreal. So wanted to see if true, nope nice clean gravel no smell, no debris no caking.
