Hello! When we built our pond 3 years ago we were just winging it, with intermittent help by searching the posts here. Things have gone relatively well, but my water plants haven't really 'exploded' in the past 3 years, despite having plenty of room to grow. Reading through these posts, I wonder what I should have down on top of the liner ro make a more hospitable growing environment. The base of the pond has a rock layer, but only about 1 even layer, no real depth. The ledges have no rocks at all. Originally we were really struggling with algae of all kinds, and my husband was hesitant to add more crevices for sediment to accumulate. Since installing our barrel filter, we've seen a huge decrease in algae and sediment, and I wonder if now is the time to properly finish out the pond. What should I have on the bottom of the pond? Should I be planting my ledge plants in a layer of gravel versus keeping them caged in pots?
