Why do we need to do water changes?

[Geraud]

This looks really good! How big is the tank, is that the 65?

The most important part on changing water is vaccum all the fish waste thats just for me.. If you dont have any fish i think you can get away with it.

Over time, usually 5-10 years(varies depending on how much you feed/how much rock/sand you have), the rock/sand becomes saturated and then the tank starts having corals dying since you've been doing the same thing for so many years and the only reason why it has been kept in balance is because the rocks/sand has acted as your natural filters, but those filters are full now.

Dam, I am a little overdue. :scratchch

Isn't that the skimmers job?

Skimmer is only going to get whats in the water column. Not on the sand bed or on rocks.
