Hmm.. not really following. Now sure how that's different than doing a water change? Take old water out, put new water in, dirty water in the display mixes with new water. Same principal or am I missing something?
If you take out 50% of the water in your system and then top off you did a 50% water change, if you added 50% new water and drained the rest you just did a 25% water change.
