Check this site for information on culturing daphnia and microalgae (among
other things): www.aquaculturestore.com
they sell cultures and media and are fish people friendly. They have culture
information archived.

Hi,

I have successfully used canned pumpkin (pure pumpkin, not pumpkin 
pie filling which has spices, etc.) which is significantly cheaper 
than baby food.  I just took a little and mixed it in a glass of 
water.  Any small pieces not suspended are eaten by the snails I have 
in my moina tanks.

For the last 6 months, I have been running a green water culture 
indoors.  A 30 gallon tank with 72 W of compact fluorescent lights 
(on 24 hrs/day) and 6 goldfish (4" - 6" long) provides enough green 
water for two 15 gallon tanks with moina cultures.  The green water 
is so thick you can not see the bright goldfish in the tank if they 
are more than about 3/4" from the glass or top of the tank.  Any 
green water removed to feed cultures is replaced with wtaer from 
nearby fish tanks which helps keep those tanks well changed.  The 
moina cultures will turn a yellowish color after all the algae is 
eaten.  I keep about 10 gallons of water in each of the moina tanks 
and remove 2 - 5 gallons a day per tank replacing it with 2 - 5 
gallons of green water.  This "forced" water changing (else the tank 
overflows) keeps the water fresh and the culture thriving.  Also, you 
do not have to worry about overfeeding like I occasionally do when 
using sweet potato, yeast, or pumpkin.  You can also let the culture 
go for a couple of days and it will soon bounce back once you start 
feeding it.  Neither the green water nor the moina have come close to 
crashing during this time.

Ken
