will it work on green water algae

No. It works on algae growing on rocks and sides of ponds.

Is this product safe for wildlife? And can i still use beneficial bacteria along with this? thanks!

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.

Is it safe for birds?

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.

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?

follow directions and should not change balance of bacteria. sprinkle granules directly on string algae areas.
