RE: Daphnia and Green Water



The recent posts about Daphnia's abilities to cure a tank with suspended
green algae intrigued me. Over the weekend, I obtained a bag of Daphnia from
a fellow member of my local plant group (thanks again Franc) and placed them
in one of my plant grow out tanks, whcich doesn't have any fish but does
have lots of suspended algae (due no doubt to me habit of keeping too many
nutrients in the water column of this tank).

Within 12 hours, the previously pea soup green water had cleared remarkably.
(and the Daphnia were VERY green). I'm not interested in getting rid of all
of the suspended algae in this tank, because then the Daphnia would starve,
but I'd bet that they could do it if given the chance. In a tank with fish I
guess the problem would be to maintain enough Daphnia to handle the
suspended algae while avoiding the hungry mouths of the fish.
