Keeping records or maintenance and tasks on the reef aquarium,

It is a good idea to keep a notebook in which you record what you did and when you did it. Do not rely on your memory! Once some time has passed, your memory can fail as to when the reef was set up, when the rock was added, how long the tank took to cycle, when the inverts were added, how many of them there were, when the fish were added, how many of them went in, what kinds they were, what the results of your water tests have been, and so on.

Unless you are an analytical type, keeping a notebook and writing down all the things you initially do to the reef will seem like a waste of time. However, as time goes on (as it has a way of doing), you will begin to see the importance and benefits of keeping the notebook. If you do this from the start, there will be a minimum of guesswork regarding water changes, water quality, how long the reef has been set up, and the monetary value of the reef.
