Re: Miracle Grow
Two cents worth. Plants do need copper. Small quantities not a problem.
I used miracle grow at about 1 Tbs per 10 gallons, every few weeks in a
marine micro algae culture. This kept it nice and green and had no
apparent affect on the marine rotifers I was culturing at the time.
Currently I am fooling around with the freshwater species and Daphnia
culture via green water. I have a 150 gallon stock tank with a bunch of
guppies, goldfish. And it is being aerated. I have added again 1 Tbs per
150 gallons. It seemed like phosphrus was the limiting factor and the
States fish hatchery would feed their green water generator (talapia )
Trout Chow, which seemed like it had the highest P content of any fish food.
