fish waste and excess food, and pollution are taken care of by protein skimming and live rock in a saltwater aquarium, and also water changes when levels exceed limits. I have over 200# of Rock in a 180gal aquarium. I have had the same tank set up for 11 years. I have kept some of my fish for 8 years, the only reason I had to get rid of them was they grew too large. My corals have also thrived in the same tank. H2O for thought. You only add pure DI water to make up for evaporation, salted water is used for water changes. I don't think distilled water ia as reactive as DI water but I could be wrong.
