ok so I have a 60 gallon tank with 3 gouramis 1 betta and 4 cory cats. there's three fake plants and I wanted to upgrade to real plants. I don't know any thing about aquarium plants. I have sand in my tank with fake drift wood and fake plants. I talked to a lady at petsmart and she said she thinks I need to add flora max to the tank. So when I heard that she thinks and doesn't know I stopped asking questions at pet smart. but I went to youtube and saw some videos were they added this plant soul stuff at the very bottom of the tank before adding gravel or sand. so does this been I have to drain my tank completely and add flora max or what.
