Joan Young –
My aquarium plants have grown much more vibrant since I started using this fertilizer. I mix it once a week with my root tabs and the greenery looks lush and healthy. Easy to measure and no fish odor. Works well in a 100-gallon tank with CO2.
Olivia Kelly –
I’ve used this for three months now and my anubias and java ferns are thriving. The color is much more intense than before. I do a 30% water change weekly and it pairs well with the root tabs.

The liquid is easy to pour and the instructions are clear. My plants have developed fuller leaves and better color. I use it twice a week and have noticed a difference in growth within two weeks.
