Pond Frog, Your Ecoshade is like my Blue vail, neither state what the dye % is. I found that a big syrnge like a turkey injecter works good. Using gloves and the syrnge keeps if off of me and gets the product out in long thin lines in the pond. Is spreads very quickly when distributed this way. I've even used a kids squirt gun, it gets it out there a long way. The only problem was it found every possible leak in the toy gun and i looked like a smurf before i knew it
