Dear marine aquarium enthusiasts! I never thought about this question, but suddenly it arose. We all change the water in freshwater aquariums. But what about in marine aquariums? Are water changes made, in what volume and how often? If so, where does this water go? To the sewage system? Doesn't it rot because of that? And what if people have several tons of seawater and a lot of used water is drained, does it harm the ecology??? In general, just questions.
