API Pondcare Algaefix Alage Control, 32-Ounce (Pack of 2)

it works instantly, safe for koi fish.

Works great. Use more often than every three days for our pondless waterfall in very hot humid weather. Actually works.

Good deal and quality. Fast shipping

Product itself worked great, however, when I received the 32 oz. 2-pack, BOTH caps were cracked. This was a drag when I went to take it off the shelf. Inevitably, a little of the product would leak out on hands/table.

So glad o found this. Wow, it really works after a few treatments. My pond isn’t big at under 200gls and sits in the sun all day so you know it was being killed with green algae. I was getting frustrated as this was my first season having a koi pond and really didn’t have a clue how to fight back till I found this product. Not gonna lie, I didn’t trust any of the reviews but try for yourself and see. I still wanna see how it does the second go around after winter is over. My water is so clear now going into the cool season that now I’m scared my koi have little to hiding spots after the plants die off. Time for netting protection I guess. Great product, still in shock at how good it cleaned this mess up. I wish I took pictures for you guys.

This stuff works the best for our Pond and we have tried so many different regimens to help with algae control. We use it throughout the whole year and in the summer one to three times a week. It doesn’t harm the fish or the plants and does a really good job And we clean the filter 1 to 3 times a week during the summer.

This product is somewhat helpful but does not completely eliminate all algae.

This is important for Algae control if you have a pond. A few days after the treatment to pond is much more clear and my UV filter can work more efficiently. Worth every penny!

It is very strong for the fish. I used the exact quantity mentioned on it but it is very strong for the fish my 2 fishes died because of it.
