Re: [APD] Green water & Daphnia
successfully cultivating green water.
Start with water pH > 7, best about 8.5. a little
limestone or oyster shell if your water isn't 125
to 150 ppm hardness. Most of the Daphnia species
don't do well in pH lower than 7.5 and hardness
less than 100 ppm Ca Carbonate.
An incandescent light of 100 watts above 15 to 20
gallons and powdered Splurina flakes usually gets
things started with genital roll over aeration.
Wait a day or 2 for the water to cloud. Emerald
green in 3 to 5 days. temp about 75 to 80. They
can take temps below 70 but molts are temperature
dependent and greater production, etc. . .
. Now one need the Daphnia to get it going.
Several good foods have been suggested and
powdered Splurina flakes works as well. Change
the water when the pH starts to drop, all of it.
You'll have Daphnia all year long.
I think the "change the water" part is often left
out. Watch the molts and the pH. The animals will
talk to you. Oh, Thiosulfate is a much better
Dechlorinater than Amquel for Daphnia culture.
Something about the Formaldehyde issue, it's
Might check out "Manual of the Production and Use
of Live Food for Agriculture" from P. Lavens & P.
Sorgeloos, Univ. of Ghent, Ghent Belgim and
references cited therein. It's a 1996 publication
from the UN. Great reference guide.
Change as much water as often as you can!
