I used RO for a while.
Ran the RO into several garbage cans then topped off with tap water.
The garbage cans were on wheels, so moving them around the house was not a problem.
Rubbermaid Brute, and I have the 32 gallon and the 44 gallon sizes. Easier to move when half full, then I use a garden hose connected to a shower to top them off when they are in the room with the tanks.
When the RO unit died (it was very old) I gave up. My tap water is fairly soft, but the Rams wanted the RO before they would breed. Cardinal Tetras prefer the softer water, too.
One of my customers kept sea horses and used a portable RO unit to start making the water for them. He had several tanks with breeding pairs.
