Water Quality problems are the number one cause for fish and coral loss. Testing your water is vital in the survival of your marine fish and coral. Every fish hobbyist should own a reliable water testing kit. Besides water temperature, some of the basic parameters that require testing on a regular basis are:

• Ammonia
• Nitrite
• Nitrate
• pH
• Specific gravity

Below is a video showing the correct way water testing should be done

You've invested valuable time and money researching the habitat requirements of the fish and corals you wish to house. Naturally, you want to protect this investment by executing a proper acclimation process once the specimens arrive at your door.

The purpose of acclimation is simple: the water that the fish or corals are packaged in has different temperature, pH, and salinity parameters than your aquarium. Fish, and especially invertebrates (including corals), are very sensitive to even minor changes in these parameters, so proper acclimation is the key to ensuring their successful relocation.

We recommend either of the two acclimation methods explained below, and wish to remind you the acclimation process should never be rushed. Also, remember to keep your aquarium lights off for at least four hours after the specimens are introduced into the aquarium to help them further adjust.

Though not a requirement of our acclimation procedures, we highly recommend that all aquatic life be quarantined in a separate aquarium for a period of two weeks to reduce the possibility of introducing diseases and parasites into your aquarium and to ensure they are accepting food, eating properly, and are in optimum health before their final transition to your main display

Once all the research, planning and waiting is complete and the aquarium is full of water and has finally finished cycling you will finally be ready to introduce your first fish.

It is important to ensure that you make the right choice though as there are some fish which are suitable to be added at this stage and there are fish which are not.

A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensive than freshwater aquarium inhabitants. However, the inhabitants of saltwater aquariums are usually much more spectacular than freshwater aquarium fish.
