MICROBE-LIFT ALGA32 Algaway 5.4 Algae Control Treatment for Ponds and Water Gardens, Safe for Koi Fish, Goldfish, Plants, and Decorations, 32 Ounces

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.

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.

For some reason, this is the first summer that I've had algae growth in one of my fountains, which I've had for fifteen years. I think it's because of the excessive heat on the west coast. The green algae grew in long strands and adhered to the walls of the fountain with a strong bond, so it was difficult to clean it manually. It also clogged up the underwater pump. Within a day, the algaecide killed the growth and a few days later I was able to "scrub" it off the walls. Now I put in a couple of tablespoons periodically and it stays clear.

I bought the three Microbe lines Pond Cleaner, Algae Control and Barley Extract, but it did nothing to clear up my pond. I ended up buying a submersible UV light and that was the only thing that cleared it up. It may work better at maintaining an already clear pond.

This brand is fantastic, and the only one I buy now. Microblift is a solid, US based brand, and I switched from API to this as the API made me nervous based on what they do to pond bacteria (the good ones) and my plants seemed sickly. This does a FANTASTIC job of controlling algae and not effecting my beneficial pond bacteria. I couple it will cleaning my water intake filter and add their PL pond bacteria. I can't recommend this enough. Excellent customer service out of Florida. They know their stuff and it is quality.

I purchased this product based its misleading , I believe, description, suggesting that it is safe to use around fish. In fact, I saw fish on the label. Upon receipt and reading all of the precautions regarding its handling, its use and being hazardous to humans, animals, fish and landscaping, I immediately returned it. The Description on this product should clearly state how hazardous it is. Firstly, it is poisonous to both humans animals, birds, and most fish. Not uncommon but not clear in its description. If you handle it, it is recommended you wear both safety glasses and gloves and if you happen to get any on bare skin or clothing that you immediately wash it. You can imagine about getting it in your eyes by mistake. I believe the description is inadequate.Also, when it is shipped, the bottle is inside a plastic bag with a zip tire on it and then you will receive it in either a plastic bag or a box. There are actually no markings on the box regarding its toxicity. If you have a pond in your yard it is likely frequent by birds, butterflies, and possibly your own pets. This Product may make them very ill or possibly kill them. When you read the complete description, it is only recommended to be used with two types of fish. Also it will kill your plants and requires that your pond be aerated. After doing my return, I went through and read some of the reviews and also found that there were many questions about its capability in doing its prescribed main purpose of killing algae. Based on the above, I gave this product a one star rating as I believe it is in accurately advertised and the posts about its effectiveness. If you buy and use this product, please be very careful for yourself, your children, your pets and any other wildlife that might take a drink of water after this is used in your pond or fountain. It states it is also damaging to landscaping so, where are you going to use this product safely. Quite frankly, I cannot think of many uses for it based upon its limitations of killing both plants and animals let alone its general toxicity.

Great product. Removed algae from my pond. Water is very clear.
