Hi guys, I am looking to convert my Fluval 60litre to real plants for a more natural look but am absolutely clueless as to how it works. I currently have black gravel but am interested in changing to sand. Do I need any kind of soil for the plants to grow? Do they need to be planted in any kind of way or do I just drop them in and let them do their own thing? I’ve read that some plants attach themselves to rocks etc. If someone could sum up the basics for me it would be massively appreciated!
