My aquarium plants have grown much healthier since I started using Flourish. The greenery is more vibrant and the leaves are thicker. I mix it with my regular water changes and it’s easy to use. No issues with shrimp or invertebrates.

I’ve tried several plant supplements before, but Flourish stands out. The plants respond quickly, especially the stem plants. I use it every two weeks and it’s consistent without over-fertilizing.
