In a few days, after placing your plants in the aquarium, you will notice some of the leaves start to melt and fall away.
This means the transition process has started. Please note the plants might look DEAD, but they are fully alive, so do not panic. Also, after a few days you will notice new growth will appear and the plant will fully change its form into submersed growth. You need to continuously trim and put a fertilizer in for the plants to thrive in your aquarium. Two good fertilizers include Easy Life – Profito and Scape Complete. All plants have specific needs but if you follow the general instructions on our labels the plant will transition well and will eventually succeed and prosper in your aquarium.
