## 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: 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.
Review: 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.

This product will work after a couple treatments but your water will only be clear for a few days and then you have to start treating it again.
