    Culturing daphnia magna in 3 gallon buckets

    So, now that I've been so obsessed with wild bettas and some other small species of fish, giving them a constant supply of live food is one of the top tasks on the list.
    I'm doing these simple cultures of daphnia in 3 gallon buckets in the patio with filtered light. The bucket has no filtration, no cover, aged tap water mixed with old tank water. The daphnia feed on the green water only. I do not feed them other means of food source.
    These buckets have been running for a few months now and they are doing fantastic. I harvest a good amount of daphnia almost every weekend. My fish go crazy for them.

    If anyone wants to start theirs, I'm happy to give you some seeding culture. I was given a small starter culture cup a few months back, so I'll pass it on to others now.

    Green water is the way to go. Very cool James, you always make it look so easy.

    That looks like a fun and very laid back project you got there. Ever since Nick Shades did a video on culturing daphnia it really peaked my interest in them. I would love for some...

    It's very easy to restart the colony, Danny. However, I would suggest to start all over again, don't keep that old water from the old colony just in case it was something in there that caused the crash.

    Let me know when you are ready.

    Danny,

    I first fill the 3 gallon bucket half way with tap water and add some PRIME. Then I add used water from a healthy tank to fill it up. I drop in a little bit of hydroponic fertilizer, leafy lettuce green formula. Stir and let it sit in the bright, filtered sun spot for a week or so. The water will turn very green from algae bloom. You can then add your daphnia starter culture and watch it explode.

    The hydroponic fertilizer will keep the water green for a long time and the daphnia will have a constant food supply.

    Once a week, you use stir the whole bucket up gently. That's it.

    Hi guys... read elsewhere on a goldfish keeping site that prime used directly kills daphnia - and that they are sensitive to certain chemicals commonly found in tap... old aquarium water is said to work best... no experience with this, but wouldn't take a chance...

    Weekly harvest. One small shrimp net scoop in one of the buckets is more than enough to feed my fish.

    We called it kutu air or water flea in english.

    You could find this easily many years back then, when i was a kid, sometime me and cousin catch some fish at sewer or creek, Gouramy ,guppy, endler ,etc.. and yes we dont really need a permit to cacth those,lol... even today, all the buceplant are still easy to get.

    Sam,

    My buckets are in the shaded patio, not in direct sun, so they don't evaporate as fast, specially if the wind doesn't blow through it. It loses around 1 inch of water about 2-3 weeks.
