TURBIDITY
Clarity is more important in sea water than in fresh water. Tropical environments
in particular contain very few dissolved solids and they are the most transparent
waters on the planet. A marine aquarium must therefore be filtered more efficiently
and to a greater extent than a freshwater tank (see Filtration, page 237).
