I’ve used this for my planted tank for three months now. My stem plants are growing stronger and the leaves are fuller. I follow the dosage based on tank volume and it works well without causing algae issues.

Good product for maintaining plant health. I mix it with my weekly water changes. My anubias and java ferns are thriving. I’d recommend it for anyone with a planted setup.

The 2L size is enough for a 20-gallon tank. I’ve noticed better color development in my plants after using Flourish Excel regularly. Easy to measure and effective.

It works, but I had to adjust the dosage because my tank volume was slightly different than expected. Still, my plants are growing steadily.
