  • I would recommend that you do some research on NPT and get a better understanding of the theory too...the more you know and understand the better.....there are some step-by-step info on them you should look into as well...just google...Diana Walstad natural planted aquariums and even getting her book she wrote on them is a great read...I use some of her method along with a twist of my own.....
