Now I'd waited a long time to get this book, which looked very attractive from the overwhelming positive reviews. Certainly the author is very challenging in some of her conclusions (don't clean out the filters too often (she dispenses with filtration material altogether and just uses a circulation pump) as this reduces the positive benefits of dissolved organic carbon in reducing heavy metal toxicity, don't bother with Carbon Dioxide injection, as you can kill off your fish, just feed your plants with excess fish food. Yes the digest of scientific research on plants and algae in natural environments is good- but it seems to be inevitably derived from North American temperate biomes (hello- do you put much sphagnum moss in your tropical fish tank- so is htere much point in relaying optimal growth conditions for this species?).
I truly wonder at her conclusion that it is necessary to be careful about heavy metal toxicity of your tapwater, but it is ok to blithely add garden soil as a substrate to your fish tank (sorry I studied land reclamation at one point- even in Britain there can be very high toxicity of some post industrial soils- for instance the now "natural" looking Peak District has a landscape that can poison off ponies!).
Her advice for establishing plants is to choose nice small well behaved fish. Well we have Richard the heavy duty rescue Plectostomus, so blanket substrate proved to be out (he loves to dig), two nest-building female moonlight gouramis who love to prune- even the Corydoras have occasionally smugly ganged up and uprooted plants as a team. As the author herself admits to killing off fish by scraping algae off the tank surface (which released toxins?)....it comes down to our well worn chant YOU JUST CAN'T WIN.
I think this book would just confuse beginners, as it is not a complete step by step guide by any means. You have to have played with the ecosytem and got past your first few aquatic disasters, before you decide whether or not to adopt some of her suggestions. It's interesting, but I want to take apart her points bit by bit to see if I can improve our tanks. I can't take all her conclusions at face value.
