[Live-foods] Rotifer cultures
I've run a culture in a pair of 10 gallon tanks. The older tank is the
one I harvest from, until the second tank reaches a high density of
rotifers. Then dump the older tank and restart it from the newer tank.
Takes a couple of weeks to flip. My daily usage consists of putting a
couple of cups of rotifer water into my (clownfish) rearing tank, and
then replacing that water with a couple of cups from the rearing tank.
Because I'm putting rearing tank water into the culture system, there's
a chance I'll contaminate my cultures. But restarting the culture every
few weeks protects against that.
I learned about this from The Plankton Culture Manual by Frank Hoff,
which I got from Reed Mariculture along with my starter culture.
Of course, I accidentally let both cultures crash shortly after raising
my first brood of clownfish. I was feeding them a preserved algae
solution, and forgot to return the algae bottle to the refrigerator.
The algae spoiled, and without food the rotifers were all dead in 48
