Expanding planted section of fish pond
Hi all, I was experimenting with adding aquatic plants rooted in substrate into my fish pond. After many tries, it has finally taken off fairly rapidly and I am now faced with the question of how I can expand the planted section of the pond.
Right now the planted section merely consists of some dwarf sagittarius, echinodorous & some vallisneria rooted into the ADA aquasoil. The pond is low tech, outdoors and lit with natural sunlight, and primarily faces the issue of algae, which seems to have improved with the addition of yamato & ghost shrimp.
What substrate would you guys suggest to add into a pre-existing fish pond like this to expand the planted tank section with minimal fuss? I will not be attempting to grow high maintenance plants with require the input of CO2. Ideally the substrate can be added with less fuss (had a lot of problems with cloudiness and water parameters with ADA), but still be able to maintain some low maintenance plants.
