i prefer to do 2.5-3g wc a week when the tank is cycled. the ammonia spike isnt that fast but the nitrate and nitrite spikes do require frequent larger wc to keep them safe for a fish in cycle. nitrite/nitrate spikes are a bit harder to cut down after the fact but a 2nd WC will get the job done. not sure on WC% to do while in fish cycling as i went with the test kit results rather than do with a water test kit.
