New 4th Edition of 'Ecology of the Planted Aquarium'!

Last summer the printing costs for my book doubled, so I decided to make a cheaper and smaller paperback version of my book. Since I had to redo all the formatting, I decided I might as well revise and update it. Took several months, but in the end I am pleased with the results. Message and book is virtually the same, but I deleted the allelopathy chapter and added about 10% new information. No earth-shaking changes!
Book is available from my distributor (Baker & Taylor Publishers) in eBook formats. Their link is: Ecology of the Planted Aquarium

Interesting update. Should we ignore the chance of allelopathy in our aquariums? Is this due to new information?

I wanted to condense my book and that chapter did not have the importance/relevance of the others in the total picture. Allelopathy between plants is just so hard to prove and sort out from nutrition and lighting factors. For example, hobbyists often say that Vallisneria and Sagittaria can't be kept together and this could be due to allelopathy. But now I have evidence that Val can use bicarbonates and Sag cannot (my new edition, Table V-4, p. 87).

BUT just after I had the book printed, I found a fantastic 2022 paper* about Neocaridina shrimp (RCS) kept with 4 substrates--either Hornwort, Java Moss, Cabomba, or plastic netting. Growth of juvenile shrimp was about 40% better with Java Moss than the other substrates. And hornwort significantly inhibited the % of berried females as compared to the other 3 substrates.

This reference supports scientific evidence that I presented in my book's earlier editions (p.44) about certain plants (Elodea, etc) inhibiting invertebrates (daphnia, etc).

Thank you for the nuanced answer 💖
