Salt water fish tanks are considered more difficult to keep than freshwater tanks because salt water fish have less tolerance for fluctuations that can occur quickly within the closed environment of an aquarium.
Aquariums, when setup properly, operate as self-supporting ecosystems. In an , artificially created or natural, every element relies on every other element for its stability. The art of fishkeeping becomes a balancing act of monitoring and maintaining specific parameters in order to keep the entire system stable. This is especially critical in a salt water fish tank because the ocean is an surprisingly stable environment. Life forms that evolved in the ocean do not have the physical ability to adjust quickly to radically changing conditions. Any changes that occur in the ocean occur slowly. For example, a quick drop or rise in the temperature of a salt can cause salt water fish to take ill, even if the fluctuation is relatively small.
• Including supplementation is normally required when your saltwater fish tank features invertebrates. So, add calcium regularly to keep marine fish healthy.
Aside from temperature there are many other factors to consider in a salt water fish tank. When the ecosystem is functioning properly, they should all take care of themselves, but they must be monitored. A typical reading for some of these parameters might be:
