Review: Works great! - This is the best product I have ever used to remove algae from the rocks in my koi pond. I have tried so many different products and none of them have taken care of the problem. This product is very easy to use and works fantastic. I can now see the rocks in the pond and the waterfall is completely clear of algae.
Review: Cleared the water quickly - I received this today and immediately sprinkled it in the basin of our waterfall and within a couple hours it was very clear. I'm sure by morning it will look even better. I will be buying this again as it is so much easier to use than the liquid. I don’t have to worry about splashing, and it is fine with the birds and the lizards.

## Questions & Answers

**Q: will it work on green water algae**
A: No.  It works on algae growing on rocks and sides of ponds.

**Q: Is this product safe for wildlife? And can i still use beneficial bacteria along with this? thanks!**
A: Ecoblast is safe for your fish, but the label states it is toxic to birds.  I only use it as a last resort - when my streams are completely overtaken with string algae, usually just once a season.  I have birds that bathe/drink from my water feature, but I have yet to find a product that works as well as this one.  It does not harm my plant life, either.  I do use beneficial bacteria at regular intervals and usually wait a day or two before starting that back up, but that is just my personal preference.

**Q: Is it safe for birds?**
A: This product is definitely safe for birds. I have been using it for about ten years to clean my pondless waterfall. It gets rid of the algae (it takes about a half day after turning back on my waterfall for the algae to dissolve) and it has not affected the many birds who drink from the waterfall.

**Q: Will this product kill my pond benefitial bacterials?  Also, how do i use this product to treat string algea on the side walls of my pond?**
A: follow directions and should not change balance of bacteria. sprinkle granules directly on string algae areas.
