My house Reverse Osmosis system have a lot of waste water so I collect it in a box at top of washing machine. Because washing machine can’t use up all of the waste water so I use 3 way connect let superfluous water into fish tank. The fish tank overflow water will go to balcony’s plant. But the RO’s waste water still too much for me then I decision to create a small Aquaponics to use these water.
