Spruce up an existing pond/stream?
DH and I recently bought a home with an established pond (koi & goldfish). First off, I never gave it much thought before, but now that we have a pond, I absolutely LOVE the whole idea. I'd rather have a pond than a swimming pool anyday!
We would like to spruce it up a bit though. The edges are flat flagstone and do not dip down into the water at all (revealing the liner). Also, there are no plant ledge for plants to disguise the edges.
We also have some cosmetic issues with the stream (also all flagstone).
The thing is, I can't find anything online showing how to change things about a pond. Anything related to 'renovation' is really just rip it out and start from scratch - so the supposed 'renovations' are really just building a pond. That's great and all, and we would do just that if we had a lot of extra $$ floating around, but we don't.
Does anyone have any experience, or know of any resources, regarding 'tinkering' with an existing pond?
