green dust killer

[willknowitall]

i have had gda for a year
recently have up-ed my magnesium ratio to 4 to 1 mg to ca
so in effect raised magnesium and lowered calcium
also have lowered my phosphate from 2 ppm to .5, 1 range
and up-ed my nitrogen a little 10 to 15ppm
gda algae fading fast, very fast
this is a variation taken from mci and a post from tom on gda and mg
just amazed at how fast and efficient the change on chemical balance has taken effect
