If you get past the basics of aquaria and want to know why certain animals or plants don’t thrive in your tank/water, or you want to do a more advanced aquascape, you hit a point where you get mired in forums filled with complex and contradictory advice, and confusion and mistakes ensue. This is the missing textbook of the aquarium you need to take the next steps. So well-documented and supported with both studies and her own experimental evidence throughout. I love how she demonstrates the complexity of our little aquatic environments. It’s always an experiment and a learning experience. There are so many variables that every tank is different - this is why understanding some principles that help drive these ecologies is important.
I definitely don’t have the chemistry or biology background to understand all of this book but what I did grasp was so useful and explanatory, and I think this will be a book I’ll refer back to my whole life. Also can’t wait to set up my own Walstad tank, as I’ve found in recent years that planted tanks are infinitely healthier, and way more beautiful and stable than unplanted, so very excited to take the planted tank further.
