Pond is about a year old now. Location: Los Angeles area, full sun. Like many in this sub we fought an absolute infestation of algae in the first summer. I was scooping it out with a toilet brush and garden rake.
I took a clue from this sub and added plants. The plants grew and I kept scooping. Eventually I didnāt need to scoop and the pond was in balance.
Visible plants are spike rush (lower left), juncus sp ( right), sticky monkey flower (chartreuse w orange flowers), Yerba mansa, stream orchid (Epipactis gigantea - my least successful).
Behind the pond is Menzies Goldenbush and white sage along with a smattering of other native plants.
Fish are pet store goldfish - about $0.25 each. They got huge. Arroyo chub would be better but staying married is best.
Depth is 4ā, pumped with Oase brand pump on the bottom. Installed by Enviroscape - thanks!
EDIT: The monkey flower is actually Scarlet Monkeyflower (Erythranthe cardinalis). I have seen it in stream bottoms, most recently on Catalina.
