If your pond is occasionally troubled by algae blooms or accumulated organic debris, here’s a way to quickly restore its natural
beauty. Blast is a proprietary blend of beneficial bacteria that breaks down the organic matter that causes cloudy water,
transforming your pond from slimy mess to clear and fresh. The ingredients are nontoxic and safe for fish, pets and aquatic plants.
Blast 2,500 Gallon is sized for smaller ponds and water features. It contains five packs that each treat a 2500-gallon pond. They
work best in conjunction with a Submersible Dispenser (sold separately) for long-lasting protection.

Last year great - this year not so much
This year I used this product too late. The green was already encroaching on our pond. I have dosed it twice so far, but I now need to do it again. We still have total coverage of algae.
Bottom Line Yes, I would recommend this to a friend
They have not worked on a large algae bloom.

The product is easy to use, within a day the water is clear. I did need to treat twice, but overall I would recommend
cleaned up my ponds
from Santa Clara, CA
Used the product as suggested, slightly more the first time. It cleaned up the debris in my ponds and has kept them clear. I intend to use this product in the future.
No change, product did not work
from Albuquerque, NM
I gave this product two chances, and both times there was absolutely no improvement in the algae in our medium sized water feature. I used the highest potency, the "blast" as was instructed on the box. Very disappointed with the product.
Didn't work for me
from West Chester, PA
As directed I put in two packets to shock my tiny pond. I didn't help. The water is still green.
Does not work
By Garden Boy
from Leonardtown, MD
It has done NOTHING for the algae in our Pond. We still have as much today as we had three weeks ago when we started using it. I have used the shock AND the maintenance at the same time with no results. Still trying and will reload it but we are NOT happy with this product right now and feel like I wasted my money!
