Is it necessary to make water changes in a marine or reef aquarium tank regularly?
Yes, it is necessary to change water in any aquarium. How often and how much depends on the biological “load” (how many fish or animals per volume of water) are kept. A general rule is either 10% every other week or 25% a month. I am in the process of setting up my first saltwater aquarium and was wondering if a power head was needed even if an under gravel filter system is not used. Good circulation in a marine aquarium is important, and even more important in a live reef tank. It wouldn’t hurt to run a small power head in the tank in addition to regular filtration. If you will be doing a reef tank, you’ll need more than one. Be careful however and don’t get too carried away. Every pump you add to a tank contributes to heat in the aquarium.
