There
is a large variety of other aquarium items and accessories available for
aquarists to choose from, but only some are absolutely necessary. You will want
to have enough air line tubing to run between the air pump and the air stones,
as well as some extra air stones. Over time, air stones begin to clog, which
reduces their efficiency and causes unnecessary wear on the air pump.
You
should also have an extra set of replacement diaphragms on hand for the air
pump. If not, your dealer can replace them for you when they wear out. Some
hobbyists like to be prepared for larger problems. If you are willing to make
the investment, a back-up pump and even an extra heater or filter provides
insurance against equipment failure.
