Not a dumb question. Usually everyone eventually asks why water changes are so important.
Well many thinks occur in a reef tank or any salt tank for that matter. Water changes are a means to keep things stable, mimicking ocean conditions.
Heres a short list of what water changes do:
1) remove waste through siphoning
2) export of any nitrate, nitrite, ammonia
3) export of toxins this includes toxins from coral warfare
4) removes depleted water and replaces it with water enriched with calcium, alk
, mag, and all other major, minor, and trace elements
5) removes excess CO2
6) introduces oxygen rich water
7) allows you to tune the water parameters easily
These are just some off the top of my head. Ammonia, nitrite and nitrate are not the only things being produced or used in a salt tank. Also nitrate is constantly being produced a some rate.
