This is a lot of text but I�d appreciate it if you read it thoroughly. I get asked a lot of questions on daphnia culturing so I�m trying to cover a lot of information in this auction. Daphnia are really easy to culture�this may all sound complex but it isn�t.
Auction
A two liter Russian red daphnia strain already established in a two liter bottle, a bag of additional daphnia to fill up the box, and a jar of baby food. Use the additional bag of daphnia to try and start your first larger culture. Shipping is included in price, and is shipped in a medium USPS priority box.
This two liter isn�t going to produce a lot in terms of harvests, but it�ll live for a year or more as long as you keep it at room temperature and give it some light. Place it on a windowsill that gets good filtered light or put a small florescent light on it.
Culturing daphnia is easy, but getting a culture started gives some people trouble because if your water isn't right you'll kill every daphnia overnight. If the larger culture you are trying to start fails you still have this 2 liter to continue harvesting from�then keep trying until you get the hang of it.
Guarantee
Live delivery is guaranteed. For a DOA box I will reship at 'no cost' to you once.
TWO LITER CULTURING
The purpose of this two liter culture it is to give you 'many' opportunities to get a larger culture started. With this mini-culture simply suck out most of the adult daphnia and add to your larger culture. If you fail at starting the larger culture you still have the two-liter culture to try again.
Whatever you read on the internet about daphnia being difficult is silly. I�ve had several cultures going for two years without one crash. My large indoor cultures are only 20 gallon laundry tubs, gravel, and snails. I feed them baby food. People that think they are difficult likely didn�t follow one of the below rules. The only read trouble you can get into is starting a new culture with water that isn�t old enough.
Tap Water:
Use only water from an existing healthy fish tank that hasn�t had a recent water change, and water coming from a planted tank is even better. If you don't follow this rule you will kill your culture. Daphnia are very sensitive to additives in our water. Don�t use nasty aquarium water or water that has been treated with any chemical�good aged water from a healthy aquarium only. If using tap water let it age for at least a month. Having a live plant in the water will also do wonders.
Air:
Heavy bubbles and current will kill daphnia. Use an airstone or sponge filter placed near the waters surface with only a faint trickle of bubbles coming out.
Feeding:
Be careful not to overfeed your culture as this fouls the water. This isn�t as important for a large culture because they can recover quicker, but for this two liter culture only a drop or two every week of baby food is plenty. A drop is a water sized droplet and not a glob-drop. As long as you have a light on this two liter culture there is little need to add much food.
Population:
Don�t allow your daphnia population to explode. When I see a large swarm I always harvest heavily from the adults from both my large cultures and my two liter culture. I use a fish net with larger holes which catches the adults and allows the young to slip through the net. I remove 90% of the adults when harvesting, and then sit the culture a week or so while the daphnia babies grow. In the two liter culture you should only see few adults in it �as long as there are young daphnia there is little need for most of the adults as daphnia start giving birth within days. A large swarm of daphnia looks cool, but it�s too much of a load on the water. Harvesting the adults lessons the load and allows more baby daphnia to grow which increased overall harvests.
Below I�ll explain how to start a larger culture, but for this two liter bottle culture you need to:
1)Add the gravel I include. I don�t ship the bottle with the gravel in so the daphnia don�t get damaged during shipping.
2)Place it somewhere that�s room temperature. A culture temperature in the sixties is good.
3)Place it somewhere where it gets a nice amount of diffused sunlight. A screw in florescent light on it also works great, but be consistent and keep it lit several hours each day. Don�t allow direct light to hit the culture as it�ll heat it up�just good diffused light.
4)Aeration isn�t needed but make sure surface scum doesn�t develop as it cuts of oxygen. If it does build up dip in some unbleached paper-towling to absorb the scum. If you choose to add an airstone place it right at the waters surface with only a trickle of air coming out.
5)If you keep it well lit there is no need to feed the culture. I�ve had one of these in a grade school all year that�s been kept on a windowsill and with it sealed�without ever being fed. If you do play around with feeding add a drop of baby food�a tiny drop and not a glob-drop. Every week add another very tiny drop. If the culture starts to get funky cut back on feeding until cleared up.
Every week remove most of the adult daphnia to try and start a larger culture. To make it easier to work in you can cut the top part of the bottle off with a sharp pair of scissors. Put it somewhere where it won�t get tipped over by kids, cats, or clumsy friends.
STARTING A NEW LARGE CULTURE
Step 1) Start with a 10 to 20 gallon tank, but any larger sized container would work.
2) Add a �� of river gravel from a hardware store. Don�t use aquarium gravel.
3) Use water from your most healthy fish tank along with a tiny amount of muck from the gravel. Don�t use tank water from a tank that�s had a recent water change, is nasty dirty, or had chemicals added to it.
4) Add some snails and something for them to eat. They are very beneficial to culturing daphnia. Getting them started and laying eggs will allow them to grow with the daphnia culture.
5) Place a sponge-filter or airstone just near the surface. Turn the bubbles down to a trickle.
6) Maintain a temperature in the 60�s as daphnia aren�t a tropical creature. Higher temperatures substantially increase yields, but until you get the daphnia touch keep the temperature in the 60�s.
7) Plants are helpful as they help keep the water stable�just like in a fishtank.
Once the culture is established and growing you�ll feed them enough to lightly tint the water green. When the green tint is gone in a week or two feed again. If the water looks like it�s getting �funky� cut back on feedings until water quality starts improving. A ten gallon tank will eat 1/8 of a jar of baby food each week.
Every three months do a very minor water change. Don't remove much bottom debris as we don�t want to throw off the water chemistry. Stable water is what�s important to a daphnia culture. Replace the water with water from a fish tank that hasn�t had a water change for a couple weeks. Don�t pour it all in at once�add it over a few days so you don�t throw off the water stability.
Once you have the �feel� of culturing daphnia this stuff is simple. If you are good with water stability culturing daphnia are very easy. I have cultures going for years that have never crashed. This is an easy culture, just pay attention to not make a sudden/drastic change that will crash your water. If you keep your culture water stable culturing daphnia is easy, simple, and very rewarding in harvests.
