There is another room that i dont show with my resevoir and RO unit, quaranteen tank/holding tank etc. Ive always got 250 gal of prepared water ready. I cant stress enough how nice it is to never need to do a physical water change. All that is needed is to keep the RO water up to standards PH/GH/KH etc and let it go by itself. I change out about 200 gal/week and dont spend any time actually removing and replacing the water.
