The dye works great. However, you should be aware that the powder is extremely fine -comparable perhaps to printer toner or charcoal powder. It's almost like smoke. This means the powder will blow all over you if you're not extremely careful. We were very pleased with the product, which comes in a water soluble bag that is packed into a sealed aluminum pouch. Unfortunately, however, the inner bags were all damaged (perhaps during transport) and so it was almost impossible to remove the inner bag without producing a cloud of blue smoke. Tossing the bags into the lake then also was somehow problematic. Because the bags were damaged, the dye blew out of the bag when throwing it into the lake. My suggestion is to open the sealed packs very carefully inside a bucket and then deploy them closer to the edge of the water instead of throwing them out into the middle of the pond or lake. It would be good however, if the PondPro could perhaps look into the packaging of the dye and improve it to the point that the dye would stay completely sealed within the water soluble bag until it actually hits the water.

Finally! I gave up on WSP pond dye inside a foil wrap years ago. I had no complaints about the quality of the dye but often some of the contents leaked out and led to some blue nightmares ,lots of others online had the same experience. I switched to double wrapped WSP, a vast improvement but the odd little issue. I was promised this new inner wrap was more solid. Bottom line, this is awesome stuff ,great colour great coverage, the inner wrap has a whole different solid feel ,not recommended but after using the first package, I was so impressed I threw the next couple with my bare hands. No issues and you could see that the WSP took a few more minutes to disintegrate. This will be my new go to pond dye. Finally, my trout made it through our hot dry summer. I credit night time aeration only and the shade provided by pond dye and yes,the dye helps with predators, cormorants fly over and no longer bother to land.

Great product. This is my second year using the product to help control weeds in our large pond. The pond looks great and the blue colour looks very natural. As a bonus the customer service has been excellent.
