Best Uses
- Clearing algae from pond
I have a small patio pond, about 60 gallons, that I could not clear the algae from. First packet of Blast I didn't see any result, so I used a second packet about 1 1/2 weeks later. Cleared up the water completely. No algae at all now. It seems you need to use more than the suggested dosage to get results, however the result is good. The product is a bit pricey, but does the job.

Best Uses
Our pond was not in bad shape, but did have some algae blooms that I wanted to take care of before it got bad. The product did not work as well as I thought it would. There are still blooms, no more new blooms, but it didn't take care of all the ones that were there. I feel that the product is expensive for the results.
Water is still unclear after several months of use and doubling the dosage. Used this product along with the aquaspheres. Giving up on this combination of products and trying something else.
Pros
- Easy to apply
Cons
Best Uses
- 14- 12 acre pond
I applied the Blast according to directions and within 3 days began to see improvement as water qualtiy improved and algae began to disappear. Within 3 weeks it was like a different pond, very nice looking! I highly recommend this product.
