I'll probably culture Moina only when I can start a successfull greenwater culture.
XD Same sp. but different behaviors spotted. Interesting...Maybe ours are the same species as they sound similar.
My larger seed shrimps don't bother the shrimps at all (maybe its due to the fact that the other shrimps will eat them once bothered ?) My shrimps and snails are all pretty indiscrimminate, just like this saying," After some time, pets will take after their owners or owners will take after their pets." If you ask me, I'll say its a bit of both.
Yeah what I mean is that in the batch of daphnia you net out, there are already a few (lets say 2-10 daphnia) in the starter you're taking from, so when you start the culture and things turn out bad once you're unlucky...
Do you culture Daphnia or Moina anyways? What is the size of the tank, if you don't mind sharing.
PS: Does anyone else know where to get copepods from? Still looking for a good price that isn't above $5... @_@
Hmmm... Unless those ostracods or resting eggs have the ability to cling on the daphnia else I think the possibility is quite low. I only net out the adults(mid-large size) for the new culture. I have 2 size of sieve, 1st sieve will filter out the 3-4mm adults while 2nd will filter out the 2-3mm. After netting them out, I will inspect for any visible contamination then rinse it and do a last inspection.
I used to have copepods invasion in my culture too, but solved the problem as the source is highly possible from a pond sample which I used to culture green water or another possibility is from the infusoria.
I culturing both. Now more of Daphnia Pulex than Moina. Moina is just a small culture to feed my rasbora, 1-2L jar. For Daphnia, will be 2g tanks and 2L containers. For more info, you can refer to this thread, http://www.aquaticquotient.com/forum/showthread.php/120375-Which-LFS-still-selling-live-daphnia-aka-boon
Then that's pretty strange... Also thanks for the information
Yeah.. @_@ Still trying to figure out the source. Trying to keep my setup as simple as possible to find out the source. No problem, anyway thanks for sharing your experience.Then that's pretty strange... Also thanks for the information
One last thing, if you ever get invaded by copepods, I'll be willing to take them off your hands... or tank.
Where's the pond that produces green water in SG anyways if you're willing to share?
I haven't see them appearing in my cultures for months. Maybe you can try hay infusion or soil infusion, there is a chance you might get some copepods. My walstads tank had a lots but I had decomm it. Or you can try pond water. Just leave the pond water in a bottle(can be airtight). I collected water from toa payoh town garden and the park beside kk hospital. Copepods did appear after weeks. XD I can't guarantee above method with 100% success. For the pond water, I collected 4times and 2times copepods did appear.One last thing, if you ever get invaded by copepods, I'll be willing to take them off your hands... or tank.

As for the pond that produce green water... It's more of greenish brown instead of green. I just trying to see if I can culture some phytoplankton out of the pond sample. Well.. the result isn't good. XD shifu fireblade's green water is the best. Miss his green water. I still trying to figure out ways to culture green water too.
I'm currently trying out dried lawn clippings but so far its been producing some strange, spidery web layer on the water surface and blurry water for the past three days. Also soil infusion uses plain, unfertilised soil right?
I have heard about a method of culturing green water whch simply uses tank water in an airtight container and facing the sun. After a few weeks, it should start to turn green. I too believe this is true as I went down to a fish shop and saw them selling bags of bettas living in a nicely colored green water. Pity the betta, but in love with the green water. Apparently shop keeper said they didn't change water therefore the suspended algae. Some crazy magic water they got there to produce such nice green water....
Those should be fungus and bacteria. The problem with hay infusion will be the smell. It can smell like garbage. Try not to add too much hay. If the infusion is too strong, then dilute it.

Yup, it can be simple but that only works for small culture. Also I am not sure if I don't have luck in it, I hardly can get pea green kinda green water. So I think thinks it only works to a certain extend. Still exploring...
That makes sense. It really does smell like garbage too. I've tossed away a batch as the thing stank to high heavens and decided to simply try out the method of leaving a jar of tank water in bright sunlight. This is a rather small jar so hopefully once it works out, I can start seeding other bottles to get a constant supply of green water.
Maybe starting a small culture and then using this 'starter' culture to seed other tanks/containers? I've seen tanks of healthy goldfish purposely kept in green water tanks to promote good growth. You can apparently do the same with 5G tubs/buckets if the fish is healthy and there's plenty of sunlight.
I heard my name being mentioned.. :P...
my nice green water tank is gone...
but I got another tank of green water with angels :P
my shrimps tank also suddenly boom alot of seed shrimp... damn ugly... sian..
throw in mosquito rasaboras, the seed shrimp disappear overnight.. and when I removed the mosquito rasaboras, the seed shrimp reappears again...
wonder if pygmy cory will eat that or not and also will they eat my shrimplets...
Bern C, show you something....
anyone interested to collect?
green water fall in.. :P

But for large culture, best is to have aeration, else the phytoplankton will congregate in one area. Also if lack of CO2 and sunlight, it will turn brown and culture die off. Didn't water parameter and nutrients will yield different kind of phytoplankton and algae.
The airtight container I have encountered culture starts to turn brown. The best is like shifu fireblade, able to maintain a few tanks of green water.
WOW!!!!!! You have stock up your new batch of green water!!!!! XD But I haven't stock up new batch of Daphnia @_@ few weeks back restarted my cultures and still growing the culture. Will let you know again when I have stock up my Daphnia.
>_< Why all my fishes don't eat seed shrimps. I only can remove them manually to reduce the population. I never see my mosquito eat seed shrimps but they go for smaller preys like copepods and dero worms. Until lack of copepods in the tank then they learn to eat dry food. But if they able to eat seed shrimps, isn't that means that they're able or might eat shrimplets?
I thinking of getting some cory to fight the seed shrimps after I shift my shrimps to new tank. @_@ I super anti-seed shrimps now!! btw your seed shrimps same sp. as ours, the white 2mm seed shrimp?? Yeah cory should be a better choice if they do eat them as they will dig out the seed shrimps hiding in the substrate.
not sure if it same species...
this is the best I can get..
Maybe that'll happen, but from what I've read and seen online people will maintain a few 1.5L bottles of green water and start a new culture every 2-3 days as to prevent crashing and to ensure fresh bottles of green water for their culture every alternate day. I plan to do that instead of using a tank to culture the green water actually. Also, is C02 really necessary? Online stuff and vids always say that using fertilizer (like Miracle Gro) helps green water reproduce faster. The aeration for bottle can probably be done by cutting holes and using the air line to pump in air through from what I've seen.
Bad luck bro, my mosquito rasaboras eat everything (from egg yolk to ostracods) but they like bullying my RCS. I used to see one of them nip the shrimp's tail and try to drag it (somewhere? ) but the adult RCS is like D: and runs away. All other fishes, no matter the size, will eat shrimplets. Apparently the only one that doesn't is the Oto, but that fish only eat algae anyways (and is too fragile).
I doubt that pygmy cories will be that effective in eating seed shrimps as they are bottom feeders while the seed shrimp will literally run all around your tank (s).
Also, very nice batch of green water you got there. How do you maintain your green water if you don't mind sharing?
By the way, can I have some of your green water stock? I'm culturing some Moina here
PS: That's the same species as Bern and me you've got there. I wish I could suck up all the seed shrimps and bring them back for my pipefishes. They love seed shrimps.(And so do I)
XD Hard to tell... probably it's the same sp.. Your tank wall has thick algae for them cling. Same happened to 1 of my tank but after cleaning away the algae they usually stay at the substrate savaging or swimming around. Hmm.. I was thinking is it due to the calcium in the water that cause my seed shrimp shell to be so hard that my small fishes avoid? I maintain my GH at 7-8.
As for small bottle culture, you required to manual aerate it by giving it a shake daily or couple of time a day. For 1.5l bottle, it's better to have aeration unless you don't mind brownish green culture. It's really hard to get pea soup kinda of culture. It also gotta take a week or more to harvest the culture. Yup.. like plants, CO2 will helps to promote their growth. They do respire too.
I only stick to 500ml bottles to culture green water. Also, if you are not using aeration, i find that it's best to place the bottle horizontally so to have larger surface area.
XD It's also good that my small fish are not interested in seed shrimp so I don't have to worry about them eating my shrimplet. I not sure about my guppies and endlers but my rasbora will leave the new born shrimplets alone and have no interest in them even they swim by. As for adult, endlers at times are just curious about the adult shrimps but never see my guppy or endler attack the shrimp before.
Yeah.. Oto is sensitive... Initially I lost 2 of them as my tank isn't mature enough and I realized my mistake of picking unhappy otos from LFS. XD It's best to pick those with a round belly.
really can't stand the sight of the seed shrimps.. so off I went to C328...
yesterday after I throw in the fish (Sundadanio axelrodi)..

video taken this morning.. think all seed shrimps went into hiding...
Hm, but C02 is too troublesome for me. I think I'll stick to fertilizer. I've seen an online vid with a guy maintaining a few bottles of pea soup/emerald green water in 1.5L bottkes with lighting and an air pump. It worked out pretty well for him if you ask me. @_@
Lucky you. My old Neon Tetras, Endlers and Guppies love chasing and eating shrimplets. I lost ten overnight when I added the fish in.
I doubt the seed shrimp'll all be gone though. Once the fish is gone the ostracods will return. Also, your tank has alot of algae- you don't use otos or nerite snails?
look at my video... all seed shrimps think went hiding in the gravels.. so cories might be able to do the job hopefully...I doubt that pygmy cories will be that effective in eating seed shrimps as they are bottom feeders while the seed shrimp will literally run all around your tank (s).

As for green water, I do not have any secret... it comes from my angel fish bare bottom 2 feet tank.. maybe light and high bio load create the green water, filter is sponge filter. maybe the o2 from sponge filter helps...think most important is light, the tank is just next to the window and then my lights is on from 6pm to 12am, so maybe long hours of light. no CO2 for this tank
you are welcome to collect the green water from my corridor.. I leave it outside to water my land plants...
But there's always a chance of 1-2 ostracods left unless you leave the fish in the tank permanently.
I suspect its the high lighting plus bioload from your angels. People also use goldfish to produce a nice green water in tanks/bucket/tub for their cultures. Very long hours of light too seems to help culturing green water.
Where do you live & when can I collect anyways? Do I just bring my own container or grab one of yours? (:
Anyway, I don't think the seedshrimps are being eaten by the fish... just that they are all hiding... out of sight is out of mind...
I stay Tiong Bahru area..
you can grab and go..
but the water is in container since Sunday. not sure still ok or not. covered and under sunlight..
Using CO2 system is optional. Air pump actually do its works by maintaining the CO2 at atmosphere level and circulating the water. With more CO2 will be better as it speed up the growth. Without air pump, gotta shake shake and it won't be as green.
XD Recently experimenting on some magical powder for airtight bottle culture.
Yeah.. neon tetra quite aggressive. Last time use to keep it and keep seeing them nipping on others tails. XD Not sure about my guppies and endlers.. I think my guppies and endlers will go for shrimplets too but at least they don't go into the heavily planted areas to hunt for food. So I am not so worry about them eating my shrimplets.
XD You can try feeling the seedshrimps to you angels. If angels able to eat small snails, probably it will eat them. Seed shrimp shell is as hard as snail shell.. hopefully it's not harder. @_@ I read an article that some ostracod can survive after been eaten by fish and pass out. http://www.lbm.go.jp/smith/facts.html#9Anyway, I don't think the seedshrimps are being eaten by the fish... just that they are all hiding... out of sight is out of mind...
