- I like to keep more than one culture going in the off chance that one bucket crashes, i'll always have a backup, or two. This will be a lot less work when I get a culture of live algae going, but for now, this works fairly well! No filter, no heater, super cheap!

To filter out daphnia I just use a reusable coffee filter to strain them out with. The mesh size is probably the same as a brine shrimp net but has a bigger basket. The dirty water is used to water my plants. I hot glued a ring of foam to the top of the coffee filter so it'll float if I want to float it for harvesting them by pouring cups of the culture through it to "trap" them in. That makes sucking them into a turkey baster a piece of cake!
You can feed them any kind of oil cake (ground nut cake, peanut cake, mustard cake....residue after crushing their kernels upon extraction of oil) in a very small quantity just 5 to 10 gram in 5 gallon of water with daphnia culture. They will multiply like crazy.
That would be much easier if you use a dense fish net which is what I use. Then all you have to do is turn the net over in the other bucket. You're making yourself a whole lot of extra working doing it the way you are.
Unbelievable amount of work. Absolutely annoying approach. More biodiversity - more stable and more simplicity. I think, all these "gunk" can be eaten by snails and black worms and other creatures like that.
Thankyou!! I did the same thing however I found it easier using a 5 gallon paint strainer.
That really was a succ succ succ success !!
Great video Greg
Beautiful Lime Green Endlers!
good effort! try green water it help daphnia to multiply too.
Thx for the tips Mr Greg.
Btw guppies in your tank is wild fish in my area jakarta indonesia.
They're wild fish in Jakarta ?
Uh that's not good . They're not from that area .
@@royalspin yet they are free food source for predatorybfishes and ate tons of mosquito larvae
Excellent video, sir! Thank you! These look even better than BBS for my guppies. The straining shells and removing salt is a pain in the ass! This looks way easier. Plus, no filter, heater or air stone?
Can you do a video about the stocktank? on how you do water changes/what chemicals you use? what you feed them? That would be amazing!
MrPianoplayer2011 due to overwhelming demand, i'll shoot a stock tank walkthrough video tonight, stay tuned!
***** thanks man! Best youtuber :)
@Greg Jones, what do you do with the detritus when you change the water as you are showing here? Since daphnia produce cysts constantly in case their vernal pool environments dry out, you may be throwing out culture starter material. AKA Cysts.
Also, I am curious what you would think of culturing daphnia using bird wastes in the water? I am sure the algae would grow incredibly fast, so wondering.
very good - easy effective - thx for sharing
Why not use a *turkeyblaster* to pull out the debris in the bottom? Looks when you spin it around it all collects in the middle for easy extraction.
Ffocsi he did....
Yeah slightly overkill for the whole process . I use a regular mesh net and transfer them to a different bucket but make sure its aged water with algae present. To get them all bunched y together use a flashlight or other light source and aim it at a focused spot which makes it much easier to get them with less hassle than all this he's doing. They're a good indicator of water quality and many studies have been done using daphnia . I prefer to leave mine outside to get natural sunlight and rain water but I have them shaded or inside during the summer .
Great video, very informative. Tanks Greg!
Would it be okay to use algae wafers?
boy those fish aren't hill stream loaches, such a strong current!
Welldone idea
Thanks for the information sir.
Is that Daphnia from the culture you got from Bill at PVAS last month? If so yours did better than mine. I got a new batch from him at NECA this weekend. I also got a copy of Mike Hellweg's book. His recipe is: 2 parts ground wheat or rice bran, 1 part each Spirulina powder, Chorella powder, Soy flour, 1/2 part powdered infant formula and 1/4 parts each paprika powder and bakers yeast. I am going to give that a try.
No air pump? What do you do to circulate the air?
nice video....Im suprised your daphnia don't go into shock as you are essentially doing a 100% water change. I feed mine largely with green water algae which raises the PH of their water pretty high. Also my green water culture is always warmer than my daphnia tank which I keep at around 70F. which makes me have to drip acclimate each water change.
Would this work if there's little floaters in it think its algae & the little floating plants need to get rid of all of them bsides the daphnia & mine are super small still .
Where did you buy that materials to get inside daphnia?
Do you think a large marina hang on box with a constant 200lph flow from the small pump I have running on it would support a live culture?
Lewis Fromholc the first thing i tried was starting a culture in a marina box and i found that due to the water turning over, all of the suspended food gets flushed out and they either starve or you end up polluting your fish tank heavily. The 5 gallon buckets seem to work well. When it gets warmer out i'll start a 150 gallon stock tank culture outside with algae as food and rainwater as topoff
Why does general debris cause a crash?
IceTurf any crap on the bottom will cause an ammonia spike, since these buckets don't have a filter, it's best to remove it weekly to avoid a crash
lol-it doesn't, he is massively over complicating the whole thing.
What did u add to create it
how often do you replace the water? Everyday? Also I plan to feed a pinch of active yeast to the daphina every 4 days is this good enough for them?
i swap water once a week and feed as little as possible, that should work, keep multiple cultures in case one crashes
How much food and percentage? Do you change 100% water? Details!
I would swap them with the help of a torch and net.
Really cool man!
do you use air pump?
What was in the new bucket of green water? I know you said "new water" but what made it green? Spiralina powder? Do daphnia do okay with a shock to clean water that quickly?
+Meg Ryan i feed live cultures of green water / algae which don't pollute the water
+Greg Jones (Greg's Fishroom) Ahhh...that you made yourself? using Just eater and sunlight? Thanks for responding so fast :) Have a great day. love your vids!
Excellent. Well done.
Wouldn't it be easier to simply siphon them into a net?
wow amazing new knowledge for me thanks bro💙💙💙
Can you buy the food online? can you put them in a 1 gallon tank.
Will my shrimp eat these as well?
awesome and Thanks!
Hey Greg.
How's it going..
Mate what do feed your daphnia ....
Yeast + spirulina? Anything else in that powder mixture?
hashim shaikh that's it!
What do you feed the Daphnia to make them more nutritional for the fish
Max Arsenault algae, yeast, etc
Thanks for the fast reply, I guess I was just wondering if you added anything extra to the yeast to "Gutload" the daphnia?
Yeast is food, daphnia eating yeast would be gutloaded, right? I like algae better though, seems like a better balanced diet
Most say aeration is needed, some say only large bubbles, this one says no aeration, some say 12 hours of light, some say 24 hours of light, some say no light needed. Some say clean debris, some say put in debris, some say mix of lots of different foods, some say only green water. Some say small water change, some say 50 percent, this one says change all the water, so much conflicting information, still don't know what to do. Maybe it doesn't matter what you do, they are so resilient they will deal with whatever you do....my guppy girl just ate one of her babies, I need my daphnia culture to hurry up and arrive.
Honestly the most successful method is giant outdoor pond with green water and no flow, the larger the better
@@gregjonesonline and do you ever change the water in this giant outdoor pond? I do have a pond, it's currently full of water plants and duckweed. I think the water might get too warm in summer. I was told I need to keep them cool.
@@Jen.K rain water should be fine outdoors, the plants may out compete the algae they need, 2 ft deep should be enough for temp
@@gregjonesonline Thank you, I could clear out some of the plants, or make another pond. I set up 2 inside tanks for them today, so will see how I go. Might transfer some to the pond when the weather warms up a bit, it's winter here right now.
what is that plant called hanging from the side of tank i would like to get one myself
java moss
Hi, Greg: Great videos and I am a long time subscriber. Where, (do you recommend,) do I get some daphnia culture? I read a lot of reviews of certain seller and either the eggs do not hatch or there are others in there that actually eat daphnia. Thanks,
+Bob Best place to go is to a local fish club auction and see if anyone has any for sale, otherwise you may find some on aquabid, or you can buy a really expensive batch from some place fancy like carolina biologic
+Greg Jones (Greg's Fishroom) Thanks,
that was awesome!
Nice..thanks.
In how many Days you add fresh water to this Daphnia culture???
How do you "Gut load" the daphnia?
+John Carlson feed the daphnia right before you feed them to your fish
What's Gut loading?
Why put them in so slowly?
Nicely done bro
excuse me, Greg. would you like to try a new system for raising daphnia?
of course! send me a private message, thanks
Eros Kaw teach me plss
hey if that new system works please make a video LOL thanks
Eros Kaw soo whats the system?
Hi eros. Do you mind sharing your system with me as well?
nice
You have a tank full of Venezuelans!!
can i feed dead daphnia to fry??
Jignesh Tamore freeze dried yes, rotting, no
thanx..
please, what do you use to feed the Daphnia?
Do daphnia cultures need to be aerated?
most would do better with aeration. But fine bubbles will kill daphnia.
In a word....no
Can we culture daphia without culture
no you can't. They just don't simply exist like aorms.
I legitimately thought Seth Green was talking
Thats their calcium source in nature.
Can u do a video about your aquatic turtle tank
here in the Philippines we put chicken poop they feed on it and they multiply
That sounds like a bad idea.... that way you could get salmonella in the water and kill the fish.
most fish are about as resistant to salmonella as chickens are, if not all.
your comment made my day .. Bravo dave
deb stor sir gud am maliban tar ng manok ano pa pwede pakain
sound good i live in N.Y.C i gues pigeon poop should work, i have a prize winning white king pigeon and is a true pet. they bond very close to people.
gut load ?
Gut loading is when you feed your live food nutritious food like spirulina powder and then immediately feed them to your fish, more nutritious for the fish
thanks , going to try your bucket method tomorrow , cheers
Спасибо тебе, человек, теперь я понял как отделить мусор от моих дафний
PURE GENOCIDE
use a net, much easier
I want to learn how to produce or create daphnia in a gallon?anyone there!
+Frank Azcarate daphina do better in larger containers, 1 gallon may be too small
Daph-neah. we called them Daphey, of course spelling is Daphnea but i don't thin the a is actually pronounced, no big deal, just my silly input. it all the same no matter
Terrible amount of work. 👎
In my place this fish is live in dirty place...
I dont understand why this guys breed that fish?
You let it eat? Sorry, i dont know english. You cant write, please.
I disagree. That little debris will not cause a crash. I have cultures in 5 gallon buckets going without cleaning the bottom for 3 plus years. I change 25 percent of the water a week and only feed green water. Typically cultures crash from over feeding
how much do you feed for 5 gallon?
