API POND ALGAEFIX Algae Control 1-Gallon Bottle

1) Make sure you know the volume of your pond2) Make sure there is plenty of aeration3) Dose as labeled as often as labeled4) As long as other plants are now established they will now eat the nutrients before the algae doesThis seems to be the steps that work for me every year. Late spring after the plants are all back I hit the algae with this stuff and the water seems good for the rest of the season. Just make sure if you have fish watch the O2 levels.

Ordering supplies from local fish stores can get really expensive, so I decided to try Amazon—and I’m so glad I did! I was able to get all my aquarium supplies at a much more cost-effective price. Great selection, fast shipping, and everything I needed for a fraction of the cost. Highly recommend for fellow aquarium owners looking to save!

Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation.

I used this when we first put our pond in and it would keep our pond crystal clear. For some reason I changed to a different system a few years ago and it has never worked the same. I am so tired of draining and cleaning the pond! So I bought this again, and after the first dose, my water is clear and the algae is losing the battle! I anticipate that my next dose will help with the algae on the rocks on the bottom of the pond. I bought the big bottle so I can continue using it faithfully.

It took about a week to kill all the string algae and turn it into mush. I'd been battling with string algae for a year. About a week of applying this every 2 days, the string algae turned to black sludge. I had to clean out the strainer and filters several times as they caught the sludge, but it's way better than dealing with the algae. Now, I apply it once a week and it keeps the algae away. I'm able to clean the pond and it stays clean.

It doesn’t grow green algae, but there is brown stuff everywhere. Even stain the fountain Brown.

With the right dose you will have a clear and clean pond. Very happy with this product.

Once a weel and the koi pond is crystal clear
