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 culture 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
1)A two liter culture previously started containing daphnia, cyclops, and dero�and possibly paramecium. Comes with a jar of baby food.
2)A bag with additional daphnia and mulm to help inoculate a larger culture with dero & cyclops�and most likely paramecium. The paramecium aren�t included in the auction but you�ll likely get them�I just can�t ensure I capture them as they are elusive to catch.
Why all these in one culture? The daphnia and dero simply function well with each other. In my personal cultures I try more for the daphnia, and the dero are like snails and help keep the culture clean. The cyclops are tiny and I don�t bother with them, but they inoculate my tanks and help feed fry. For larger dero harvests its best to start a separate culture as they like it �yuckier� than the daphnia prefer.
Don�t expect to see many dero in the two liter culture. I keep 2 two-liter cultures to observe and usually only see a few dero at a time�but they are there. Prior to shipping I make sure I see daphnia, dero, and cyclops. In all my tanks, not containing catfish or loaches, I always have cyclops and dero living in them.
This two liter isn�t going to produce a lot in terms of harvests, but it�s great to help you get a larger culture started because it will always be available.
Put a light on this and it�ll thrive for a year or more. This small culture will continually produce daphnia, dero, and cyclops so you have many opportunities to start a larger culture. To increase the organisms add a drop or two of baby food each week.
The daphnia are Russian Reds. If you aren't familiar with dero worms they are a relative of tubifex worms and about 1/2" long. These two critters are beneficial to each other as the dero worms eat decaying matter such as dead daphnia. Culturing these two together is a common practice. The culture you receive is mostly daphnia with a few dero. The mulm from the bag will also contain dero so you�ll have plenty of them�they just aren�t overly abundant in a healthy daphnia culture as they like their environment yuckier(for lack of better words). If you overfeed your daphnia culture the dero will explode, but this isn�t good for the daphnia so don�t do it in this bottle culture.
Culturing daphnia & dero is easy though getting a culture started gives some people trouble because if your water isn't right you'll kill every daphnia. If they die you still have this 2 liter to continue 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.
Shipping
-72 hour heat packs are available. I check your weather prior to shipping and decide if a heat pack is needed.
-Mailed USPS in a medium sized priority box.
-Shipped when weather permits at my discretion. They ship fine in colder weather so unless it�s very cold expect shipment.
TWO LITER CULTURING
Daphnia are the most prolific and what I focus on, and will explain this in terms most suitable for daphnia. To get enough dero to harvest they should be cultured separately. 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. You can introduce the dero worms by adding pieces of plant from the two liter.
Daphnia & dero are easy to culture. Whatever you read on the internet about daphnia being difficult is silly. I�ve had several cultures going for over a year 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.
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.
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)When you get the culture tip it to suspend everything, and then add the bag of gravel. Once the gravel is in don�t tip it again as you want the dero to get established without the gravel being disturbed and crushing them.
2)Place it somewhere that�s room temperature. A culture temperature in the sixties is good.
3)Place a screw in florescent light on it and keep it lit several hours each day. Natural light is great but not so bright it heats the culture. If you get too much algae growth cut back on the 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)Add a drop of baby food�a tiny drop and not a glob-drop. Every week add another tiny drop or two. 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. Introduce the dero from plant clippings or mulm from the gravel. 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.
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.
