## Description

MICROBE-LIFT ALGA2.5 Algaway 5.4 Algae Control Treatment for Ponds and Water Gardens, Safe for Koi Fish, Goldfish, Plants, and Decorations, 2.5 Gallons

Review: Completely changed water clarity!! I HIGHLY recommend as long as you use sparingly. - I read the reviews and I was nervous since we recently added new Koi after losing some big ones last year. We have a 200gal pond. I don’t know why but despite doing everything our pond was completely taken over with algae. I did SMALL AMOUNTS every day for about 6 days and today I couldn’t believe I could see the bottom of the pond and all the fish 🥹 I used this in tandem with Dr. Raifyas Pond Refresher and wow! No fish loss. If you use a couple cap fulls a day, you’ll be good. On the 5th day, I used a bit more and was able to see to clean the excess algae and buildup off the sides and surfaces and did it one more time today. Highly recommend.
Review: Great for algae in a planted tank - This works great! I had some green hair algae all over my tank and didn’t want to get shrimp if the water quality was bad enough to cause that hair algae, so with one dose of this and a couple water changes the algae melted right off. I do have to say with more delicate plants in the tank like Monte Carlo or pearl weed, that they did turn a little yellow after using this, but it did not fully kill them, so they were able to recover fine.
