Captain Specifications Review: Works as claims - Works great getting rid of the thick algae that grows in pond in the early spring. Very easy to use in a sprayer it does not kill the fish. Review: Works great!! - Why did you pick this product vs others?: Used the product on Wednesday and again on Friday diluting 32oz to 2.5 gallons water. All the algae was gone by Sunday so extremely satisfied. The ducks were swimming in the pond less than 12 hours after I sprayed and they as well as fish are all fine. The dog was swimming Saturday and he is fine. One thing to note, do not under any circumstances let your wife read the information on the label attached to the container as she will associate this product with a nuclear explosion. ## Features - Captain targets all major algae types-planktonic, filamentous, and chara-for total water clarity and balance in lakes, ponds, and reservoirs - Fast-Acting Algae Solution Used by Experts: Can see reduction in algae growth within 1-2 days - EPA approved with No restrictions on fishing, drinking, swimming, or irrigation.
