I planning on setting up my 55, FOWLR. I want to get a RO/DI unit but dont know how it works, I mean I have no clue what so ever, Anyone wanna give me a crash course? I dont want to buy water when there all this tap water going around for free!!
How do RO/DI units work?

Water, under pressure, passes through a 1 or 5 micron prefilter then through a carbon block filter, up through a Reverse osmosis filter then through the Dionization filter then out to your container. There is also a 'waste water' line coming off of the RO Filter which you can either put down the drain or collect for other uses (watering plants, washing cars, etc.)
That would be a crash course. Most of the scientific stuff happens in the RO and DI chambers. That would require more than a crash course.

So when Im gonna fill up my tank I can connect a RO/DI unit to my kitchen sink with one end going down the drain and the other end going into the tank, then i take the that water and mix it with salt. Is that the idea?
Here's an answer to a like question I read earlier:
It is based on the principles that osmosis works on. Basically on the unpurified side of the osmotic membrane you create positive pressure (pressure from the water supply line). That allows molecules of water to move towards the lower pressure (purified) side, until the concentration of the solvents (all those chemicals that you want to remove and that are left on the unpurified side of membrane) becomes high enough, so that osmotic pressure (water molecules trying to go from low concentration solution into high concentration solution) becomes equal to your household water pressure. By flushing down the drain those solvents that are left on the impure side, you are decreasing the osmotic pressure so that the water can continue flowing across the membrane. That is why it is called REVERSE osmosis - you create and maintain pressure on the unpurified side that can overcome the osmotic pressure.
HA!
