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 dont 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.
