I’ve used Algae Killer for two months now and noticed a significant reduction in green water. The algae stopped growing after the first application. I also reduced my aquarium’s light exposure, which helped maintain the results. Easy to use and effective.

It worked well on a small algae outbreak in my freshwater tank. I added the recommended dose and saw improvement within a day. I plan to use it regularly during summer when light exposure is high.

My pond had persistent green water, and after using Algae Killer once, the algae disappeared. I followed the light reduction advice and haven’t seen any return since. Very satisfied with the product.
