Water Changes When Nitrates consistently read zero?

[Eb0la11]

Im just wondering about this topic since Ive been testing my water and I have almost no nitrates whatsoever even after like 3-4 weeks of not changing my water. It seems like my chaeto and DSB seem to be taking care of my Nitrates.

So this makes me wonder - are there any reefers who don't do water changes very often if at all? It seems like dosing, topping off evaporated water etc is enough but has anyone ever run an aquarium for an extended version without adding more fresh salt water?

Im sure some trace elements would eventually go real low, once we dont dose for, but what if we dosed everything? Just trying to have a discussion, Im not going to go and do this, but just wondering if anyone else has?
