Water changes

[ReefOcean]

Who here is lazy with the water changes? I haven't done one in 3 months. The first month was just laziness but since there was no changes in my water quality (I still test, dose and top off daily) I decided to keep it going as a little lazy experiment. Upon searching the web, it appears I am far from alone. Many people go months...years..without doing a water changes.

Keep in mind, I have one fish in about 50 total gallons of water. I have a sump with more LR and macro algae and everything in my tank is pretty mature (rock is about 4 years old even though the tank relatively new). I have seen some posts, where people claim they have a much higher bioload and still maintain perfectly healthy SPS colonies with zero water changes for an extended period of time.

Who else does this?
