Product Overview

I recently had the opportunity to try out the Crystal Blue Liquid Copper Algaecide, and I must say that my experience was overall quite positive. As a professional reviewer who has tried out a plethora of products, I can confidently say that this product is one of the better options on the market in terms of its effectiveness and ease of use.

The Crystal Blue Liquid Copper Algaecide is designed to control many types of algae such as filamentous, chara, planktonic and swimmers itch. It is 100 safe for humans, fish, livestock, pets, birds, swimming and irrigation when used as directed. However, it should not be used in Koi, Goldfish or Trout ponds. The algaecide comes in a 128 fluid ounce bottle with an item weight of 9 pounds and dimensions of 6 x 6 x 12 inches.

In terms of ease of use, the product was quite straightforward to apply to my pond. I just had to calculate how much I would need based on the size of my pond one gallon treats 1 surface acre 1 3 ft deep and then pour it into the water. Once applied, it began working almost instantly and within a few days I noticed that some of the algae had already begun dying off.

The value for money offered by this product is also great given its effectiveness in controlling algae growth. Although it may seem pricey at first glance, when one considers how much time and effort is saved from having to manually remove any existing algae or take other preventative measures against future growth then it s clear that this algaecide is actually quite cost effective in comparison.

Overall, I would highly recommend the Crystal Blue Liquid Copper Algaecide for anyone looking for a reliable solution for controlling algae growth in their pond or lake. Not only does it work quickly but it s also easy to apply and offers great value for money compared to other algaecides on the market today.
