I absolutely recommend this to ANYONE searching to increase their knowledge of aquatic plants and the chemistry and biology involved in nature aquariums. It may contradict what you’ve read on forums! A must read for enthusiastic hobbyists.

"Ecology of the Planted Aquarium" by Diana Walstad

I have this book and I highly recommend it also. It’s great and very informative. It does lack information on high tech set ups tho. But it’s still a great read. 9/10
