So, I have an established aquarium and I want to put live plants in it. My plan is to take out the existing rock and replace it with Eco complete and tahitian moon sand. I was just planning on getting everything laid out and ready. Then take the fish out right before I add the Eco complete and then add everything else. Is this an ok route or do I need to have an extra aquarium ready because the aquarium I am putting live plants won't be ready for a couple of days? Not sure what do if anyone can help it would be much appreciated.
