It really does, imagine how often you do water changes, just guessing but I'd say an average of good aquarium keepers do 50% every week or two maybe a little longer. And then think about the fact that a true professional aquarist, with a perfectly kept tank at the perfect parameters with live plants and a powerful batch of beneficial bacteria will only change his water and vacuum his substrate maybe once a year! Nothing cleans a natural pond or lake, it cleans itself on a permanent cycle. Fish and turtles waste puts off ammonia, which in turn feeds the bacteria, which puts off No2/No3 nitrates and nitrites. This in turn feed the plants which removes any co2 and replaces it with oxygen, which the fish breath. Other byproducts and waste are eaten by scavengers and microbes which in turn feed smaller fish which then have waste which produces ammonia which feeds the bacteria and so on and so forth for ever and ever. You can reproduce this exact system in your tank and once you do, you will never want to go back to the old weekly water change deal
