Here’s my little patio pond. I have 2 of them. The other I am still deciding what I want to do with it. One has a small group of rosy barbs and a small group of flagfish. It currently has a jungle of Anacharis as well as many other plants, and in the summer, floating plants. I know this is controversial, but I don’t have a filter or bubbler for it. I’ve had it up for a year or so, and everyone is doing great. I let the algae roam free, no matter what kind it is. I built it inside of an old wine barrel, lined it with thick pond liner, and filled it with pea pebbles. Beautiful pond in the summer…not so beautiful in the winter.
