Review: This stuff kils any algae that it touches. - This product is very fine, almost like a dust, so you have to spread it on a COMPLETLY calm day, or it will blow around everywhere. With that said, it also works extremely well on killing algae. We have had a big algae bloom this year on area ponds, more so than I have seen in a long time. I walk around the shore of my pond with a small pail of it and simply cast it out with a nitrile gloved hand while wearing a dust mask. You don't have to put it out heavily either, just a light dusting and that nasty geen stuff is turning brown within an hour or so. This type of copper sufate is actually made to add to livestock feed as a trace mineral for the animal, that's why it so dang fine. But boy, what a bargain price for the 50 pound bag! It will go a very long way, I won't use all of it this year and will have plenty left for using it if I need it next year. Just keep the unused portion it it's bag in a 5 gallon plastic bucket with the lid on it, out of the way of children and pets.
Review: Pond algae treatment. Works! - Luckily, my pond is fed by a small stream that runs year round. I add this upstream and let the mixing and dissolving occur while it makes its way to the pond. About 5lbs per acre foot of water. Once a week. Could dissolve in a bucket ahead of time, but I let the stream do that work. Turns out to work quite well - about 1/3 the cost for similar copper delivery using pond treatment liquids vice this feed grade powder. We’ll see how the season turns out. Filamentous algae browns up in about two days after treatment. Fish are fine and thriving.

## Questions & Answers

**Q: Can you broadcast the crystals over the algae pads rather than the dissolve and spray method?**
A: yes you may but with fine crystals, you may have some trouble as it is powder.

**Q: Should you turn your aerators when you treat your pond? Or does it matter**
A: I used mine for killing roots in field tiles. For pond use, our sportsman's club puts it around
the edges of the one acre ponds and lets it settle, without mixing it in too much. That's where
their problems are. I would imagine if your whole pond is a problem, turn the aerators on. Just my opinion.

**Q: Can this be used as tree stump remover?**
A: No idea I use it to kill weeds around lake

**Q: How much crystals would I add to a 20 gallon sprayer to spray for algae?**
A: The ratio to add to 5 gallons of water is 3 pounds of the product.  So you can add 12lbs to that sprayer.

### ⭐⭐⭐⭐⭐ Very fine crystals - easy to dissolve in water
*by W***E on September 23, 2019*

Easy to handle and very fine. Cannot be broadcast as there is an extreme amount of fines that just float off in the air. As good as it gets if you need to dissolve crystals in water and very cost effective. Only minor dust while pouring into a 5 gallon bucket. If you are using in large sprayer, I premixed in water before pouring into the sprayer but I had to stick my hand into clean out hole of the 25 gallon tank to agitate the fines off the bottom so that the pump would pick them up, and you will want to remove the pickup screen or it will clog. Comes packed in a plain cardboard box which is adequate and easy to open. The bag itself is a standard paper lined with plastic and it does have a vent so a small amount of dust will escape as the bag is being handled. Best opened with a box cutter.
