  • Moving, and selling my water changing station, I built this for my reefer 425xl, and couldn't imagine life without it lol.
  • Store RO/DI in right tank, use left tank for mixing salt water, and then pump water to tank.
  • Cost me ~$800 in parts ($270 for containers, $220 for pump, $100 for ball valves, and other misc parts).
  • PM me for more details or questions.
