My aquarium plants have grown much healthier since I started using Flourish. The green color of the leaves is more vibrant and the plants are more robust. I mix it with my nitrogen supplement and it works well together. No issues with shrimp or other invertebrates.

I’ve tried several plant supplements before, but Flourish is the most balanced. My anubias and java ferns are thriving. It’s easy to dose and doesn’t cause any algae problems. I use it once a week with a bit of phosphorus supplement.

After switching from a generic plant fertilizer, my tank looks much cleaner and the plants are more active. The iron and magnesium in Flourish seem to make a noticeable difference in leaf development. Safe for my shrimp community.
