I have created a micro pond
This started last summer as an experiment with clippings that were going to the trash. One year later, it has grown into a fully functional pond with zero input from me other than adding water.
Ludwigia Repens, Dwarf Sags, Hornwort, Water Wisteria, Monte Carlo, a bunch of little snails, 4 male guppies to eat the mosquito larvae.
No light, heater, filter, no fertilizer, no algae.
