## Description

Flourish Excel, 2 L / 67.6 fl. oz.

Review: Works very well - Plants really take off after using for a couple days. Algae died off and isn’t able to take hold. Great product when used accordingly. Makes plants super healthy and will need to also make sure you give the plants root tabs to keep up the health and size.
Review: Good product - I used to have algae problem. So I started using this product every other day and now all my algae problem went away. It really works. But warning, my vallisnaria plants don’t like it, they all died. But it didn’t affect my other plants, they all thriving. Once my small bottle was finished I ordered this bigger bottle to have more for a better price.
