API Algaefix, Algae Control, 16 oz.

I use this in my outdoor full-sun water fountain..... (just water in it). If I add this to my water every time I replenish it I do not have an algae problem... .. i can definitely tell a difference if I didnt use it. I will get an abundance of growth in like 3 days. One bottle lasts me the whole season. The only thing I do not understand is that on the label it says it's safe for fish and "wildlife", but toxic to domesticated pets. So just be aware of that.

It is hard for me to get to the back of a large fresh water tank so I use the Algeafix to help places I can't get to. Works fine and some of my fish are over 15 and they are fine.

[This review was collected as part of a promotion.] I used API Algaefix and I am very satisfied with the results. It helps clean green water and keep my aquarium clean. I have small aquarium and since I use API Algaefix I don’t feel I need clean my aquarium to often. It simply to use and works affectively to keep water clean. I would definitely recommend it

[This review was collected as part of a promotion.] This water makes maintaining a betta tank completely stress-free. I love that it is pre-conditioned and pH-balanced so I don't have to wait or worry about measuring chemicals. My betta became noticeably more active and energetic right after the water change

[This review was collected as part of a promotion.] We have a small fish aquarium that often gets algae, and this product took care of it. We have an algae eater fish as well, but adding this along with the algae eater fish took care of it all. Definitely recommend!

[This review was collected as part of a promotion.] Excellent for helping with my fish tank. I was struggling to keep it clean recently, but this has been a game changer. Easy to use and works so well to make sure my aquarium is clean and well taken care of!

[This review was collected as part of a promotion.] Easy to store. The bottle does not leak. This is a good value product for your algae needs. With our filtration system, we do not need much to keep algae at bay. I am looking forward to seeing how this does in our other tanks!

[This review was collected as part of a promotion.] I tried API algaefix and was happy with my results. I really appreciate that the lid is also the measuring cup for the amount I am suppose to use. I don't have to worry about miss placing it. According to the directions, you use it every 3 days until you can skim out the algae. It definitely help my tank.

[This review was collected as part of a promotion.] I'm not super impressed. This seemed to not affect my fish at all, but did affect my plants and not all survived. The water is clearer, it appears cleaner, but that's only because of so many of the plants are gone. You have to dose it a lot, so if you're not good at doing something every few days/remembering i wouldn't reccomend trying. It didn't work much for my black beard though. I had high hopes.

[This review was collected as part of a promotion.] API Algaefix seems like a good idea, following instructions it may take multiple treatments to work. I did appreciate that it is space for my fish and live plants. I didn’t notice much difference after the first treatment and plan to keep trying every 3days as instructed to really clean and clear the algae.
