love it- but read the warning label

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.

Algeafix

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.

Excellent

[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!
