Cutrine-Plus Granulated Algaecide - 12 lbs. Professional-Grade Algae Killer for Lakes & Ponds, EPA Approved to Control All Types of Algae (Planktonic, Filamentous, and Chara)

We used this for our personal tank and within 24 hours half of the algae was gone! After 42 hours we had almost incomplete clean tank! I do advise to do this with no fish in the tank

It killed the Buttercup in the lake.

Unfortunately this product did not have the effect as advertised. I pulled the moss/algae from my pond and used an app to identify the exact species. It was common sago pond weed and algae…. I measured the exact square footage and used the recommended amount on 1/2 the pond. Came back a week later, almost no difference. Used the remainder of the product on the same stretch of pond (double the amount suggested), and came back a week later…. Still little-no difference. Followed instructions perfectly.

Total waste of money

Easy to apply and the price is surprisingly cheaper than any store.Thank you

I learned that algae that grows from the bottom requires pellets or granules and floating algae requires liquid. Follow that regime and your pond will clear up. Have purchased this product every year to keep up with any new growth.

Expensive but works well

We put granules in according to dosage for our pond. The very next evening brown dying algae! Will continue useage!
