First published in 1970 containing everything needed to manage the carrying capacity of a reef aquarium. It also contains a formula for the determination of the carrying capacity.
Our first marine aquarium was based on the publication of Frank De Graaf,
Frank De Graaf.

Later published in the US
Graaf, Frank de.
Marine Aquarium Guide. Harrison, N.J.: Pet Library, 1973.
The book contains all information for setting up a marine aquarium, much later better known in US as " The Dutch System". Frank de Graaf was never credited for " The Dutch system". Our first marine aquarium was an original so-called "Dutch System", set up in the early seventies!
