The stuff I bought was a white powder from my pond supply place (no not
THAT white powder) I don't recall the brand name, you mix it with water and
use a spray bottle to apply (I used one of the bottles left over from the
$13 herbal spray)...looks a little ugly for a couple of days then washes
off....it kills the aphids (I understand) by cutting them to shreds as they
crawl across the leaves because the d/e is an abrasive but too small to hurt
the fish...

How do you apply the DE? Is it safe for fish?

Is it safe for the fish if the herbal stuff gets in the water?

I have had good luck with both the herbal & the D/E, I prefer the D/E
cause
the herbal stuff is expen$ive.
