Exactly my practice. I have a couple tanks to which I manually add rain water 
or RO water, depending on the rainfall. The gradual mixing seems to not be 
important. I now just dump a couple quarts of rain water in when I think of it 
or I test the TDS. The fish seem to like the stimulus of a sudden rain water 
event. That's what happens in nature. I do not replace more than 1/3 of the tank 
water with rain water. If I am doing a more major change, I premix the rain 
and dechlorinated tap water. Actually, as time goes by (8 years now), even 
Maratecoara lacortei do not seem to need as soft water as when they were newly 
derived from wild fish.
