EQUIPMENT AND ACCESSORIES

An aquarium can only function properly with reliable equipment. It must be easy to put into place and to use and it must offer every possible guarantee of safety, paying particular attention to the potentially dangerous combination of water and electricity. There is sufficient variety in the aquarium trade to supply hobbyists with a reasonable choice, on the basis of their particular needs and means. It is pointless (and expensive) to think big; besides, simplicity is often the byword for efficiency and success.
