yeh.. as amph has said, its not that the water your gonna use is on par, it needs to match up with your old water.

if you just jump in and do a 100% WC, then your fish, and everything else in your tank will get stressed from the difference in water parameters. there would be a ph swing, temperature, possibly alk and all other parameters.

its always better, if you want to do a 100% WC to do them in smaller increments as to not have such a swing in parameters. by doing smaller ones, it gives the water time to assimilate with the rest of the system, thereby less of a change over a longer amount of time.

true its not as efficient as a 100% WC, but whats more important, getting it done quick, or getting it done in a manner that will least affect your system.
